I recently upgraded my tx2500 from Vista to Windows 7 (32 bit), and ever since some of my computer's features haven't been working. What I've noticed so far is that when I swivel and flip my screen around to go into tablet orientation the screen no longer inverts automatically like it used to. Additionally, the buttons on the side of the screen that control tablet settings and manually flip the screen no longer work. When I press them nothing happens. Also, while the stylus still works for writing and as a cursor, when I use my fingers to push on the screen nothing happens, which is disconcerting because prior to the upgrade my screen was touch sensitive. Has anybody else had this problem/are there any drivers I'm missing or can reinstall that will fix it? When I originally upgraded to Win7 I was told I needed to uninstall my HP quick launch buttons, but I'm not sure if that has anything to do with the problem I'm experiencing. Thanks for any help.
