Quicken has become unstable

I am running version R31-12, It is running extremely slowly and If I don't wait until the last operation fully completes, an extra mouse click causes quicken to go into an infinite loop. I have tried validating my file, super-validating my file, going back in time to a backup database where I didn't see this problem, and still seeing the same problem. Made a on hour accounting task about five hours. I had to close Quicken each time it occurred and restart it.
