I'm Having a problem with my mouse scroll wheel, at first I thought it was Firefox but after further research and testing it seems that my mouse and KVM switch my be the problem.
When I scroll up on my mouse it back up a page in all my browsers, needless to say this is quite annoying.
I've found a lot of info on the mouse scroll/back problem in firefox, but as I have tried all the fixes, and discovered it's in all my browsers, I don't believe firefox is the issue any more.
I then found info on a issues with driver config in xorg.conf, however, after looking at the xorg.conf file I found no mouse driver config.
The solution it talks about though has to do with how many buttons the mouse has compared to what the driver says, and what the zaxis says.
I have also found that possibly it may be the combination of my hardware.
I Have: A HP USB optical mouse wired.
An Avocent 2 Port SwitchView KVM Switch with PS2 ports
And A USB to PS2 Mouse adapter
Edit: It appears that it may have more to do with the KVM Switch as I've put a PS2 mouse on with out the USB to PS2 adapter and the problem still exists.
