When I boot up my computer, I can move the cursor with my tablet pen on the login screen with no problem. When I login and my desktop is displayed, I can no longer move the cursor around with my tablet pen. I've run diagnostics, passing all the tests (except cursor movement) and updated the drivers to the most recent 521_6a, but I'm still having the same problem even after resetting my computer. I've tried deleting the previous drivers, shutting down my computer, and allowing windows 7 to auto detect new drivers, but the same issue comes up, no cursor movement. Your help would be much appreciated. Thank you.
