This has been a problem for quite some time now (as long as I have a digital receiver, approx 1.5 years?) and it's pretty annoying if you have a zillion windows/tabs open in your browser

I'm using a MacBook Pro 2.16, Logitech Z-5400 receiver, have tried this with both 9.x and 10.x Flash versions.
Other people with the same problem? Any known workarounds that don't involve restarting my browser? Any ideas as to what could be causing this?
