I didn't think it normally used that much, but when it was hanging this time, I opened task manager and that is what it was using. Something along the lines of 1,695,000 K. I don't see how another program could make it look like sb was using more than it was, but I'm sure it had something to do with why it stopped working.
When I say the program was hanging/freezing up, I mean it didn't say it was "not responding", it didn't crash, I could minimize and bring it back up no problem.... but it would not budge past the current comment it was trying to post to and would not let me abort or pause the commenting. It just stayed there in limbo til I forced it closed with task manager. The main sb window was still actually counting how long the operation was taking, but the slow posting window just said 3 seconds til timeout, and just stayed stuck at that 3 seconds.
Anyway, I doubt this will be a regular issue, but if my previous suggestions could help prevent it from being a problem at all, then even better.
Awesome app regardless
