Comment 4 for bug 234466

I also have this problem on the same computer, an IBM x41 tablet, and using fully updated hardy heron as well. I have the exact same versions of wacom stuff and the problem is the same: after a few hours of normal use, the pen will stop functioning, when you bring it to the screen it will jump back and forth from where you are pointing to a random corner of the screen and be clicking so it will erratically click things and drag boxes on the desktop.

I haven't found one way to reset wacom or fix the problem without having to completely reboot (even then its purely chance whether or not it will function properly once booted or how long it will last) It is very inconvenient.
