F8-F12 - opening bags?

Try getting rid of all your auctioneer stuff. I had some major problems with Auctioneer lately. With just a single player, it would freeze my window for 2-3 seconds the first time I opened a bag or moused over a bag. Stacking 5 freezes together could make it real bad.

I was even experiencing a crash bug for a while. Removal of auctioneer (and all the other things that came with it) fixed everything. I haven't replaced auctioneer since then.
