For starters, I am currently using a Lenovo X61 Multi-touch tablet with the Windows 7 OS. Now onto the problem... For some reason, my Wacom pen eraser does not work in MS OneNote 2007 or Journal anymore. When I try to erase using the back of the pen, it acts like the front of the pen and just draws a line. I have checked the settings in OneNote, Pen and Touch, and the Wacom Pen Tablet settings, and eraser is enabled in all these properties. In addition, in OneNote, the pen output is very scratchy and not as smooth as before and the automatic pen/selection tool in OneNote is also not working.. I have no idea what caused the sudden change of behavior. I have reinstalled the latest Wacom Penabled drivers (5.05-7) multiple times from the Wacom website, but the problem has not been fixed. Before this freak behavior occurred, I was also using the same Penabled drivers. Weirdly, the Wacom eraser and pressure-sensitivity work just fine in Photoshop. The problem has been baffling me for days. X_X I'd appreciate any help I can get. Thanks! P.S. What I haven't tried is uninstalling and reinstalling the MS Office Suite, but I'm not sure that that would work since the eraser problem also occurs on Journal.
