whats a bamboo fun tablet ?

^^ Pen tablet. An input device where the pointer is controlled by a pen.

@legolas: Wacom has good warranty support. Is yours under warranty? If yes you should get it checked. You did after all check it on someone else's comp.

Maybe your wiring is a problem. Try plugging it into a PC from some other building or something. Might work.
