Don’t forget the KVM Switch

I have been having some fits with mouse behavior that seemed to happen at the same time I upgraded to Linux Mint 12.   So I erroneously blamed Mint 12.   The issue remained with Linux Mint 11 etc.   Some things I did in 12 and 11 would mask it but the issue would still remain.   That it was now happening in a previously stable version on this hardware was a clue.   Before I tested a new mouse, thinking it was hardware, I removed my KVM.   For some reason the KVM was really behaving badly and introducing a lot of latency when certain things happened.

Without the KVM all of my problems have disappeared.

Don’t forget to test the KVM if you have one.
