I was excited to find SingleInstance. I have a computer set up for my 3 year old to play games, and he does multiple clicks when he wants something. SingleInstance does not seem to detect/close multiple instances of Firefox. He gets 3-4 Playhouse disney sites going with overlapping audio, and it is a nuisance to keep closing the other ones. Any chance of tweaking it to handle Firefox 3 instances?
Thanks for some great software....
