Just installed CentOS 4.2 on a system that was running RedHat-9.

The system is connected to the keyboard, video and mouse through a Belkin OmniView Pro KVM switch.

After bootup, the the system tracks movement by the mouse just fine.

The unstable behavior can be characterized as follows:

1. Console is switched to a different system for a time and then switched back to the Centos system.

2. Movement of the mouse causes the cursor to jump all over the screen erratically.

3. Windows appear/disappear as if mouse-clicks are selecting things rapidly at random.

It's pretty difficult to follow visually, so I can't say in detail what is going on.

I changed xorg.conf to have "simulate 3-button mouse" set to "no".  No change in behavior.

The mouse is a pretty simple one that came with an E-Machines box and has worked fine with all of the systems up until now.

Any pointers would be greatly appreciated.
