Bug Description
When using Wizardpen with Genius G-Pen F610, pen buttons are often mutually exchanged and tablet touches sometimes completely stop working. This is because the tablet sends multiple events (event->value == 2) when holding a button while dragging the pen. The driver expects just pairs of single button-on/off events and implements the button state switching as simple toggle. This can be fixed by switching button states based on the actual event value, see the attached patch. After applying the patch buttons on my tablet work perfectly.

It looks like a hardware failure, a contact bounce, maybe.
As an alternative to wizardpen driver, you could try using the tablet with the evdev driver - simply remove any wizardpen configuration from X.org configs - it should also work.
