That won't let you get out of the vendor screen, or won't let you do anything at all except control alt delete.
Do you think this is an ancillary error that will be fixed when the other problems get fixed? I hope so because I don't see any threads about it, and it's obviously a much bigger problem than helmets or experience, not being able to use vendors at all.
I'm just worried it won't be addressed and I'll have to figure out which add on is the culprit, which would take for EVER. Hoping other people have seen it.
