● At startup, a dialog box appears 

telling you that either the driver 
failed to load or the tablet 
preferences have not yet been 
created.

The pen tablet was not detected at startup. Make sure the 

USB interface cable is securely connected and that the status 
LED on the tablet turns on when the pen tip is pressed against 
the tabletʼs active area.

● The pen display tablet works 

correctly when initially installed 
under OS v10.2.7 or 10.2.8, but 
fails to work after restart.
