RHIDE updates some things during the idle time, not the syntax highlight! 
that's a real time task. Anyways the "problem" was fixed some weeks ago and I 
put it clear in my announcement of my editor. Just calling to __dpmi_yield() 
makes the "usage" (this value is really fake) to 1 or 2% (same under OS/2) so I 
guess Robert will include it in RHIDE too. Anybody can download my editor and 
check. The main reason of releasing my editor is to test these things.

RHIDE never eats the CPU I think W95 GIVES the CPU to RHIDE if there is no 
other task to run and hence RHIDE "usage" is 100%.

We don't need to mess with these W95 settings at all.
