Q85390

-

The information in this article applies to:


 * Microsoft Windows versions 3.1, 3.11

-

If you are running Microsoft Windows in 386 enhanced mode and losing the mouse pointer when switching to or from MS-DOS-based applications, then change Device Contention for the communications port to Never Warn.

Steps to Change Device Contention

 * 1) Run Control Panel.
 * 2) Choose the 386 Enhanced icon.
 * 3) Highlight the COM port being used for the mouse (COM1 or COM2) and select Never Warn.

This is equivalent to adding the line Com1AutoAssign=0 to the SYSTEM.INI file's [386enh] section.

For more information on this setting, refer to page 247 of the &quot;Microsoft Windows User's Guide,&quot; or page 195 of the &quot;Microsoft Windows Resource Kit&quot; guide.
