Yes and Yes.
The cure is TameDOS.
www.tamedos.com
It's cheap, and there's a free trial.
Xy under Tame is a much enhanced experience--it allows a lot of screen
improving (as well as CPU saving).
See the Archives for much discussion of Tame.
I don't specifically recall this being raised before with regard to XYWin
but I have recently noticed, having just built a quiet PC, that when I run
XYWin it acts like a CPU stress test, running pushing the CPU to 100% and
pushing up the CPU temperature which sets my fans running faster so that
eventually I can hear them again. Is this normal with XYWin and if so, is
there any cure?
