Why are you checking for the Window's enabled status rather than reacting when it's pressed?

When using infinite loops with Windows GUI application, you must ensure that Windows messages are processed during loop execution. If not, you can't check for events like pressed button.

The common approach to realize such loops is using them inside an own thread (worker thread if no GUI operations must be performed from inside the loop). While the worker thread is running it should check for a terminate event that is signaled by the main thread when the button is pressed or your application terminates.
