Thanks for revising your comment 
I told you early on that I ONLY had Dugi installed. NO OTHER ADDONS. Yes, I have gone through many many permutations of trying this and that. I even ordered new memory to eliminate hardware issues. I noted some minor memtest issues, so I wanted to do that first. It did not help.
This morning again, with ONLY dugi enabled (nothing else in the addons folder) I was in WG and sure enough the game locked up. Maybe it is only happening in BG’s (?) though I did note something else, but I can see how frustrated you are Ozzi (and I don’t blame you at all)! I am just going to go an alternate route for now, and try to come back next update. I too am frustrated, but I think you have done all you could to try and help me.
(Just an add — when I locked up in WG, I logged out and as fast as I could, I logged back in with all addons except DUGI, and did not get a lockup) *shrug*
I suppose I could reinstall WoW!
