Question about 'How do I get my mouse to work in DOS programs?' Tuesday, December 30, 2003 at 10:42 am Windows 2000 Annoyances Discussion Forum Posted by CHANDLER (1 messages posted) IThis article was previously published under Q260209 SYMPTOMS On a computer running Windows 2000, MS-DOS-based programs may not have mouse support. CAUSE Windows 2000 has different program information file (PIF) settings than in Microsoft Windows NT 4.0. By default, Windows 2000 enables QuickEdit mode in NT Virtual DOS Machine (this is also known as NTVDM, Windows on Windows, or WOW). RESOLUTION Disable QuickEdit mode in the PIF for the MS-DOS-based program: Start the MS-DOS-based program. Right-click the program window's title bar, and then click Properties. On the Options tab, click to clear the QuickEdit Mode check box. Click OK. Click Save Properties, and then click OK. Close the windows and then start the program again. STATUS Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article. MORE INFORMATION If you configured the PIF in Windows NT 4.0 before you upgraded to Windows 2000, the MS-DOS-based program should work without changing the PIF. Windows 2000 does not allow NTVDM to run instructions that try to manipulate hardware or memory locations directly. Therefore, some MS-DOS-based and Windows 3.x-based programs (such as games) may not run in Windows 2000. There are presently no replies to this message.
