I get my Wacom Bamboo Pen & Touch apparently working (By using Martin Owens' PPA), but whenever I try to click and drag something -- for example to move a window -- it will only register as a click. In other words: The "button up" event is generated right after the "button down" event no matter how long I hold it in.

This is the same whether I use the tip of the pen, the buttons on the pen or the buttons on the pad.

However: Clicking and dragging works perfectly in the login-screen, both before logging in for the first time and after logging out.
