MORE INFORMATION
What the Update Provides:

The System 7.5 Update File

The update installs a file called "System 7.5 Update" in your System Folder. The new file provides the following enhancements to System 7.5:


 * improves system stability when memory is very low
 * fixes a potential crash problem when shutting down or restarting Japanese systems with QuickTime 2.0 installed
 * fixes a potential crash problem when pasting large blocks of data
 * no longer opens the wrong original when you select an alias on the desktop of a disk other than the startup disk.
 * no longer interferes with custom colors that some applications use in the Open and Save dialog boxes
 * the keyboard Power key can now be used to turn the computer off. To shut down the computer, press the Power key. When the dialog box appears, you can shut down your computer, restart your computer, put it to sleep (if it supports sleep) or cancel the shutdown.
 * PowerBook 100 series: These computers do not have a Power key on their built-in keyboard. However, if you attach an external keyboard, the keyboard Power key can now be used to turn the computer off. To shut down the computer, press the Power key. When the dialog box appears, you can shut down your computer, restart your computer, put it to sleep, or cancel the shutdown.
 * PowerBook Duo docks: Pressing the eject button automatically launches items in the Shutdown Items folder and shuts down the computer. No dialog box appears.
 * PowerBook 500 models: improves trackpad performance
 * PowerBook 150: The update extends battery life by reducing power requirements during sleep mode. It also fixes a potential system freeze problem that occurs when you use the internal modem several times without restarting the computer. The PowerBook 150 Update system extension is no longer needed and is automatically removed from the Extensions folder (inside the System Folder) during installation.
 * Power Macintosh: Native QuickDraw speeds up operations such as scrolling, image filtering, and pattern and text drawing. The updated Serial Driver fixes a potential crash problem.
 * Power Macintosh (including those with the Power Macintosh upgrade card), Centris 660AV, Quadra 660AV, and Quadra 840AV: Updated video software prevents scrambled video when the computer starts up.
 * For Performa 630 series, PowerBook 150, Quadra 630, and LC 630 (models with internal IDE hard disks): The update fixes a problem that prevents the internal IDE disk from appearing on the desktop. The problem occurs when the internal IDE disk is the selected startup disk, but the computer is started up from an external hard disk by holding down the Command+Shift+Option+Delete keys during startup. The MountIDE system extension is no longer needed and is automatically removed from the Extensions folder (inside the System Folder) during installation.
 * Quadra 700: An ADB patch fixes a potential problem that can slow down the mouse or trackball.
 * Quadra 840AV: The updated Display Manager ensures that a multi-sync monitor is set to the correct resolution when you restart the computer.

Launcher Enhancements

Launcher version 2.7 supports Macintosh Drag and Drop so that it's easier to add or remove items:


 * To add an item, open the Launcher and drag the item into the Launcher window or onto a category button. The system creates a new Launcher button for the item by placing an alias in the Launcher Items folder. The original item remains on your hard disk.
 * To remove an item from the Launcher, hold down the Option key and drag the button out of the Launcher.
 * To move a Launcher button into a new category, hold down the Option key and drag the button to a category (grouping) button along the top of the Launcher window.
 * To open a file, drag the file's icon onto a Launcher button that represents an application program. For example, you can open a SimpleText file by dragging its icon onto the SimpleText button. If the program the button represents can open the file, the button is highlighted when you drag the file to it.
 * To put a file into a folder, drag the file's icon onto a Launcher button that represents a folder.
 * To re-size the currently visible Launcher buttons, hold down the Command key and click inside the Launcher window. Then choose a new size from the pop-up menu.
 * To open a category button's folder (located in the Launcher Items folder), hold down the Option key and click the grouping button.

System Extension Enhancements


 * File Sharing version 7.6.1 improves overall performance and provides new functionality. When file sharing is turned on, removable disks and CD- ROMs will automatically be shared-except for audio CDs, which will no longer be shared. You no longer have to turn off file sharing in order to eject a removable disk or CD-ROM.
 * Apple Guide version 1.2.5 improves performance, runs native on Power Macintosh models, and is compatible with At Ease.
 * SCSI Manager version 4.3.1 will work with Performa 630 series, PowerBook 150, Quadra 630, and LC 630; fixes a potential data corruption problem on Quadra 840AV and Quadra 660AV models; fixes a potential crash problem when using some external hard disks.

 * WindowShade version 1.3.1 fixes a potential crash problem that occurs when memory is very low.
 * MacTCP version 2.0.6 shortens retransmission delays; prevents potential out-of-memory errors; makes configuring communications easier; gives you more control over the choice of server(s) to contact and the order in which they are contacted.
 * Centris 610 and Quadra 610 with the 610 PC Card installed: PC Setup version 1.0.2 is provided. (It was not provided on the System 7.5 upgrade disks.)

Application Enhancements

SimpleText version 1.2 provides the following enhancements:


 * Large documents, PICT files, and page ranges (i. e., pages 2 and 3 of a 5-page document) print correctly.
 * Page Up, Page Down, and scrolling work better with Portable Digital Documents (PDDs) and other documents.
 * Editing features (such as Cut, Copy, the forward delete key on extended keyboards, underlining, and selected text highlighting) work correctly.
 * SimpleText documents that use a system font now retain their fonts when opened on a Macintosh with a different system font.
 * In the Don't Save/Save/Cancel dialog box, you can type "D" or Command+D for Don't Save.
 * If you Quit with an unsaved document, choose Save in the Don't Save/Save/Cancel dialog box, then choose Cancel in the Save dialog box, SimpleText now cancels the Quit rather than quitting.
 * Remote program linking (controlling SimpleText with AppleScript from another Macintosh) is enabled by default.

LaserWriter version 8.2 Printer Driver

The LaserWriter version 8.2 printer driver provides the following enhancements:


 * The new Setup button in the Chooser automatically looks for the selected printer, selects the appropriate PostScript Printer Definition (PPD) file, and configures the paper trays. If you wish, you can manually configure the PPDs and papers trays by clicking the Setup button a second time.
 * The destination in the Print dialog box resets to "Printer" instead of retaining the previous print job destination. For example, if the previous destination was "Fax," the destination automatically resets to "Printer" for the next job.
 * You can tab backwards through the fields in all print dialogs by pressing Shift+Tab.
