You can post your config on this list, or send it privately to me if you
do not want to register, I'll put it into our bugzilla.

It is in novell's bugzilla, because the first person who had problems
appearantly was one of our testers.

You can pay for another developer.

I wanted to track this down (and I might even be the culprit due to my
buttonmapping patch, but I dunno why this only happens for few people),
but I couldn't reproduce this issue here easily, and I'm currently stuck
with a far worse issue and didn't have time to investigate further.

*This* is important input for me. Thanks! If there are no unusual
events, it is certainly neither hardware nor kernel related. (It might
just be that your mouse delivers the events in a certain speed or order,
so that this bug is triggered.
