I noticed that I was using a lot of extra RAM last night. I found out that for some reason, that stupid Gator thing (I don't even know what I installed that that worthless piece of software came with) was running, taking up 40 MB of RAM. And the .dll that caused it to start back up again if I killed the process was taking 30 MB. Needless to say, once I figured out what was causing all that memory to be used, it took about 30 seconds to get 70+ MB of RAM back.
