Running the debugger on some debug executable. Add a break point in some loop. Debugger breaks. Hit F5, the program continues and hits the loop soon again. Hold F5. The cycle continues a few times but then the debugger hangs.

This will be fixed in the next patch release (0.3.0.3 and later). Thanks for pointing it out!
