The problem is that you are spinning in a busy loop while the timer is running. You should check the timer stop condition in the event handler.

I am also a bit surprised that the code works. If you are using System.Windows.Forms.Timer, you should not even get into the event handler and so the counter should not be incremented. Also the counter value is not properly checked nor updated. The while loop can be transformed into endless loop.
