I noticed this morning it was taking an extremely long time to transfer a file over adium MSN to someone using MSN on pidgin on windows. I mean like super slow. I noticed when I moved my mouse over the file transfer window it sped up until I stopped moving my mouse. Intrigued, I started circling my mouse around the window. Surprisingly the transfer sped up again. It was bizarre. I tested again, and got the same behavior. So next time Adium is transferring a file way slower than you think it should, start impatiently moving the mouse around over the file transfer window. You may be surprised. I promise this isn't a joke.
