Matthias, I tried the things you suggested, but without much success. I got
Windows to use Taskmgr OK, but I can't get any Dos tasks to show up in the
Windows task menu, and I can't switch out of Windows.

The modifications I made are:
1. Added "taskman.exe=c:\drdos\taskmgr.exe" to Windows system.ini
2. Set the hotkeys for Windows and Taskmgr to be the same 
3. Set Taskmgr to run as a task switcher

I couldn't find anything else in your NWDOSTIP.TXT that looked to be
relevant to this.

I experimented with various settings but nothing worked. I removed
taskman.exe from Windows to ensure that Windows was using Taskmgr.

I would be very grateful if you, or anyone else, has any more advice on this.

Ray Greene.
