I'm currently developing a set of casino games in VB .Net. Today I was testing my blackjack game and monitoring it with the task manager. It was working ok at first and only using about 25,000 k of the memory and 5% of the cpu. Suddenly, the cpu usage went up to 100%, the memory usage remained at 25,000 k, and the program crashed. Does anyone know what the cause of this could be?
