The information in this article applies to:


 * Microsoft Windows versions 3.0, 3.0a, 3.1, 3.11

SYMPTOMS
The minimize and maximize buttons may appear as black boxes and buttons in dialog boxes (OK and Cancel, for example) may also be blackened out when you use an earlier version of the MS-DOS mouse driver with Microsoft Windows in enhanced mode. Although the Program Manager comes up, the display may have a slightly yellowish or greenish tint. This does not occur in real or standard mode.

This problem may occur on an IBM PS/2 using the PS/2 mouse with an earlier version of MOUSE.COM in the AUTOEXEC.BAT file.

This earlier driver can also cause the IBM PS/2 model 70 to appear as a CGA display.

WORKAROUND
To correct the problem, remove the MOUSE.COM line from the AUTOEXEC.BAT file. Install the MS-DOS mouse driver from the Windows disks into your CONFIG.SYS if you want to use a mouse for MS-DOS applications.
