My pen crapped out even though I have not dropped it. It stays in it's "coffin" (a fancy wooden pen case with inner foam) when not in use but the bugger suddenly did not work when I planned to use it yesterday.
It keeps selecting things on the desktop everywhere even though it's just barely touching the pad as you can see in the video. So I thought the problem is with a broken coil as described here http://abiamy.com/abiyasablogs/2008/04/06/fixing-a-broken-wacom-pen/. I guess I had to return the pen for repair or buy a replacement.
Good thing my old circa 1997 graphire pen is compatible with this Bamboo. I dunno why it worked in Vista using the latest driver (521-6a). I almost donated this old serial tablet because there's no compatible Vista driver for it.
It's not fun that the pen will just crap out like that. WACOM!!!!!!!!!!!!!!!!!!
