I'm running win7 and innerspace and having the same issue. What's happening is when you close your entire team at once ( via exit game ) sometimes they dont fully close or something and your left with an extra wow.exe under processes on the task manager ( usually its only taking up about 50mb ). So then when you go to load the next time it skips over that window in the loading process until you go manually end it in the task manager, its a new issue for me ( never had the problem in bld 33 ).
