So...

Its causing me to freeze, never had this issue beofre and all the sudden it started o thappen.

Deleted my CACHE folder, deleted my oquque files in WTF folder, and logged in and still happening.

Disabled it, logged in and now no more crashing.

Can you help me? is this happening for any1 else?
 

check to see if your capped on bnet friends.  top right of oQueue.  once you get to 98, you can crash at any time (it's a blizz assertion error)

also, what version are you running?
