Problem - T B Studio 4.5 Stopped Working

I have Toon Boom Studio 4.5. I started a new file and found that only my grabber tool could be selected. I tried turning the program on and off several times, but that isn’t working. I also pulled up an existing file with the same result. Any potential solutions? ???



Is this something new or did you always have this happen before? We would need to know what might have changed on the machine between the time it did work and the time it started giving you this behavior.
