It's one thing to keep getting a "Sorry, you didn't win" screen over and over again, but is it really necessary to have the game boo you too? These things just make me grind my teeth.  There are a couple of games that do that and I can't stand it but there are some good prizes to be had. So I've comprimised and just shut my sound off when I sweep!

I never sweep with my sound on - too many windows open!!! 

I know what you mean. I leave the sound off, it gets annoying sometimes.

Just remember, there are far worse things to get frustrated over!!   Sweep in "mute".  I see no reason to have the volume turned on unless there is something specific that I want to listen to.  This way you won't hear them booing you!
