I have tried it, and RHIDE works under Windows 3.11. As a result of this i tried
many things to get Beta5 work under WIndows 3.11, but no success. Now some facts:

1) The problem is NOT a bug RHIDE, it is a bug in the TV library or in Windows 3.11.

2) As written above, you can bypass the problem by not loading a mouse driver in
   your autoexec.bat or config.sys

3) After looking at the code I found, that I didn't lock all the code and data,
   which is used bye the mouse handler, which is installed. For the first moment
   I thought, this was the problem, but this wasn't.

4) Because I can run RHIDE without this problem under WIndows 95 and under raw DOS,
   I think, the problem is in Windows 3.11 or in the DPMI-server in WIndows 3.11.

5) Some people said, they can run Beta5 only, if the give a project name at the command
   line when starting RHIDE.

6) The problem has nothing to do with 32-bit File Access because it occours also when this
   is disabled.

An now some wishes to all users of RHIDE Beta5 or my port of the TV library.

I) If someone successfull run Beta5 in WIndows 3.11, please can you post your
   configuration (memory manager, mouse driver) ?

II) Can someone take a look at the routines in the TV library (my latest port) in the
    files 'EVENT.CC' and 'HWMOUSE.CC' and check, if I did something wrong, That I haven't
    locked all the code and data I found myself, but there may be an other reason.

III) Has someone similar problems with an installed mouse handler (not hooking the interrupt)
     when running in WIndows 3.11?
