Typecase's Font Compression Feature May Cause GP Faults

 * }

Q84848

-

The information in this article applies to:


 * Microsoft Windows versions 3.1, 3.11

-

SYMPTOMS
The Font Compression feature included with Typecase, a third-party application for Windows, may cause general protection (GP) faults and other system errors when used with Microsoft Windows version 3.1.

CAUSE
Typecase allows users of Windows 3.1 to selectively activate and deactivate TrueType fonts. If Typecase is installed, only activated fonts appear as choices when you are selecting fonts within applications for Windows.

Typecase also includes an option that conserves disk space by compressing deactivated fonts and leaving only activated fonts uncompressed.

However, if a compressed font is used by bypassing Typecase (for example, by manually adding font entries to the WIN.INI file), GP faults and other system errors may occur.

WORKAROUND
To remove or disable Typecase, do the following to ensure that no compressed fonts remain on the system:


 * 1) Run the Typecase program.
 * 2) Select the [All Fonts] entry from the Typecase drop-down box.
 * 3) Select any font in the left-side font list box.
 * 4) Choose the Select All button.
 * 5) Choose the Activate button. If any fonts are currently compressed, this will decompress them.
 * 6) Exit Typecase.

Typecase is manufactured by a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding this product's performance or reliability.
