bizarre mouse behaviour

Hi,
I'm using OpenSuse 10.2 alpha 4 and it's been runing fine for a while, this
morning I booted it up and the mouse has begun acting very strangely.
Even the slightest movement results in several minutes of activity where
windows are opened and closed, files opened applications started and other
weird behaviour occurs. It's like the slightest movement triggers a stream
of random mouse commands including clicks. I've tried replacing my usb
mouse with a ps/2 one and rebooting and the same porblem occurs. So I guess
it's not a problem with the usb port or interference on the mouse cable.

I've also rebooted without the mouse and then everything works fine. If I
wait for activity to die down with the mouse in, I can also work fine from
the keyboard. As far as I know nothing has changed. I haven't installed any
new software or run any updates. The only thing I can think of is some
weird control key combination I've pressed accidentally but I don't know what.

Please help I'm trying to get suse accepted as a dekstop OS here at work
and having to tell people I can't work isn't helping my cause.

Thanks

Mark

You want to upgrade or install the released version.

This is usually caused when the driver loses its synchronization with the
mouse. Often times this happens when switching from one machine to another
using a KVM switch. I usually dumb down my mouse support to imps
(psmouse.proto=imps on the kernel boot line) across all Linux machines (I use
imps so I can have a wheel). Then I set the driver to reset to force
resync on errors (psmouse.resetafter=1). After I switch to a machine, I issue
a mouse button 1, that will cause the error if sync has been lost and
force the reset.
