So I've had this problem since Cata, probably the 4.0 patch, but at least since Cata where inspections fail after about 2 seconds. I assumed it was just a game bug because everyone in my guild had the problem, and then the guild died out and I quit. I come back, and the problem is still there, so now I'm assuming it's actually more likely an addon issue. Before I go and delete my interface and WTF folders and start from scratch though, I want to ask here if this is something other people experience (and thus I can't help) or if it's just me (and I can help).
