Ok I had to shut off the Forum Spy Widget after having a slow down and pinpointing it to the forum widget sucking 120MB of memory and slowing my system to a crawl. Im not sure if this can be fixed but does it need to be pulling that much memory.
It's not really doing anything beyond what the normal Forum Spy does. I imagine it uses RAM in the same manner. If that means sucking up too much RAM, well that kinda sucks. I haven't had much of a problem. You may just want to relaunch every couple of days if you leave it on all the time.
