This has been a problem since Red Hat 7.whatever. The issue is with the 
IMPS/2 mouse driver. I've found that switching away from the TTY and 
back to it almost always clears it up. i.e. Ctrl+Alt+F8, then Alt+F7 (or 
Ctrl+Alt+F7). This is a "workaround" I've lived with when using any 
Belkin/Dlink/etc. KVM based on the same basic chipset with almost any 
Linux and the IMPS/2 driver. That, or you can switch to a different 
mouse driver (i.e. PS/2) and expect "normal" behavior.

HTH,
