I recently restored my Acer TravelMate C200 Tablet PC with the restore disks given to me. However ever since doing so it would no longer rotate the display with the buttons on the bezel (the Fn and Esc buttons on the bezel also did not work). I tried reinstalling several drivers from the System Disk that came with the computer, but nothing seemed to fix it. Out of luck I finally got the Launch Manager v1.10.1e off their drivers web site and installed it and rebooted. That corrected the problem and I noticed the “Change Tablet and Pen Settings” showed up again in my task manager. Not sure why the version on the Restore and System Disks didn’t work. I don’t ever recall Windows Update giving me a newer version.
