I have 2 puters my desktop is a few yrs old and is running vista on it and my laptop is only a yr old running windows 7 all programs and flash player are up to date as i am obsessed with keeping everything updated and clean of viruses, spyware,adware ect... and it still does it to me on both computers. It also doesn't matter what browser i use. I mainly use firefox but have tried a couple others and still have that happen. Also lately I have been noticing that every 15 mins my browser freezes for about 5 seconds when i am in chat. I have googled the problem and couldn't come up with anything. And since it only happens when in chat it must be a chatroom issue
