hints on KVM switches w/ X

[Gregory Bond]

Has anyone got hints on using KVM switches with XFree86?  I'm using a wheel 
mouse and moused, but something gets out of whack when I switch away then back 
to X.  Next time I touch the mouse, all sorts of weird things happen for a 
fraction of a second, then the mouse starts working OK.  This is annoying and 
dangerous because it often winds up pasting random stuff into xterms.....

Are there any hints for making this less of a problem?
