[GLLUG] Keyboard & mouse problems

[Brian Daniel Beck]

I use a USB Mouse and Keybord (Logitech MX1000, Microsoft Natural 4000) as 
well, and experience similar reactions under high CPU load both in Linux and 
Windows.  Not totally certain what causes it, but it's not Linux-specific, 
at least for me.
