Of course I should have said that I'm using RHIDE Version 1.4 (Sep 30 1997). I
 did try the 'Show free memory' option without it making any difference.

However I have investigated a little and discovered that the problem is not
 with RHIDE per se, but rather it will affect any DOS program that sits in a
 tight loop waiting for keyboard input using the bios to check without waiting:

  const DELAY = 10000;

  while (bioskey(1) == 0)
    for (unsigned n = 0; n < 10000; d++);

interestingly, on my system if I set DELAY to be 60 or less then there is no
 slowdown at all, but go to 100 and immediately I will have to wait up to 10
 seconds for menus to activate in other windows applications.

Obviously a problem in Windows 95 or my setup at least, so I'll have to try a
 more appropriate group if I can be bothered. Perhaps I should be thankful
 that's *all* that's wrong with my Configuration :-)
