Because using the shift key several times the game is actually halted by Windows (thrown back to the desktop) because of the 'Sticky Keys' problem - I don't think anybody mentioned that. This is obviously more than me just being picky.

Sticky Keys, for the record, surely has to be among the most annoying 'enhancements' ever.
