I have a $100 Wacom Intuos drawing tablet, and after a while, it says "THE TABLET DRIVER WAS NOT FOUND" when I try to open the Wacom Tablet Properties. The tablet still functions the same, but I just can't change the settings. Restarting works, but it takes a long time for my computer to restart, and it's a nuisance. How can I fix this without restarting, or prevent it in the first place?
EDIT 1/20/15: Sorry, I forgot to specify that I'm on Windows 7. I didn't think it mattered.
