A few days ago, I went to re-calibrate by pc pen input, as I have done many times before. When I clicked on "Pen Tablet Properties" the usual icon popped up on my task bar but no window opened. When I held my mouse over for a preview of the window is showed a blank (it changes between black and white) box with a button in the bottom right hand corner. Clicking on it does nothing. Then I tried opening "Tablet PC Settings" this worked, however, when I press "Calibrate" -> "Pen Input" nothing happens. I can use the "reset" function to clear calibration data. When I try clicking "Setup" -> "Pen input" it opens the correct screen, but then after I have touched the main screen with the pen and pressed enter, it goes back to the main computer screen. I have a T901 fujitsu lifebook pc running 64bit win7. I have already tried reinstalling the "pen" "pointer" and "pointer utility drivers" and nothing changed Please help. I have been having trouble taking notes in class, as it is very difficult to draw diagrams with improper calibration.
