Toon Boom is not working correctly

When I start with the program and I try to open a sample project or even create one, and the menu windows stay on screen even though I select another menu and I can´t see neither top view window nor drawing window,etc. Inmediately after, the software freezes.

Of course, I can´t do anything.



Just Mr Windows… When I chose minimize and maximize later ToonBoom gets ok :o

Thanks anyway
