hi you can an do one thing open the model popup without close button so this will make you main form inaccessible as you want hope this will help you.

The only thing I can think of is to start the timer when the main form's Deactivate event fires and stop it when the Activated event fires. However note that if you have any code in the main form which pops up a MessageBox then this will also cause these events to fire.
