We would need a little more information than that to help you. Version, single user/network, if network is this only affecting you?  Do you get an error message or does it just freeze.  What part of the program are you in when it happens?

Ooops . . . thanks, Marc.

Small law office, single station user.  No network.  No error message.  I can work within the program, just cannot minimize the window or exit the program without using Task Manager.  I am in the "time and expense" entry portion of the program when this happens.

Have you run diagnose this computer yet? You can run it from within TS, Special, Station Administrator, Options, Diagnose, or run it outside of TS with TS closed. The File is Statadmn.exe

I did.  No issues.

I would try Setup - preferences - appearance - restore all dialog settings to their defaults.

If that doesn't work I think you will need a time support or with a consultant.
