Everytime I log into a certain game I regularly play, Quantum freezes. When I type into the message areas there is a lag between typing and when the letters appear. The game freezes up on a regular basis, had to restart quantum 4 times this morning so far. It effectively prevents play on this game. (Mobsters 2030) If I have a second window open, that also freezes up. I routinely listen to internet radio at the same time. This freezing isn't always there, as it was happening yesterday. I synced everything and optimized it. Nothing seemed to help though. This started yesterday when I upgraded to Quantum. Lags are bad enough, when your playing a video game, but extreme freeze ups are terrible! I end up having to close all windows and restart firefox and log in again. My computer has plenty of memory and normally runs at top efficiency. I'm even getting a slight lag here while typing, but it is not as extreme.
