Pretty much like the subject line says. I have a 2760P that works well generally, but the cursor or hot point for the stylus rapidly jerks around an area of just a few pixels whenever the laptop is awakened from sleep mode. At least, this seems to be what causes it to happen. The twitchy/jerky cursor does not affect the touch pad, only the stylus. It makes it impossible to draw with because it causes dozens of rapid clicks resulting in dense zigzags. My work-around is to log out and log back in--I'm using Windows 7 64-bit. This restores the stylus to perfect functionality, so I know it's a software and not a hardware issue. What could be causing this? Is there a certain driver I should be using? Any thoughts would be greatly appreciated.
