Reinstalling seems to have done the trick for me, too. Thanks!

When you hit enter after "/oq fog" the command doesn't disappear, so you might be misled it didn't go through, but it does.

Disabling the fog fixed the lag in map mode, but my WoW still freezes when I charge, or even when I just join a raid if oQueue is enabled.

WoW freezing

I don't know what changed, but in the past couple of days my WoW has been freezing. All would be fine, then I go into an arena or a BG, charge some guy, and the game completely freezes. 
I also noticed that the full screen map mode is much, much laggier than normal - there's a noticeable lag between pressing 'M' and getting the map on the screen, and also my fps drops from 80 to 3 in map mode.
All these problems disappear the moment I disable oqueue, and nothing else helps.

Blank lines in premade listing

I just downloaded 1.8.2d and now when I go to "Find premade" I see these random blank lines between actual premade listings. When I mouse over them, theh line doesn't light up and nothing shows on the mouse tip. It's just a blank line.
