Yeah, I've been using IE7 for a bit now and it has been pretty stable but I get errors now and again. I am loving the tabs so much that if I wind up on a machine that doesn't have it I am lost fore a few moments.
As for news on the AW front, nothing yet. AW Steve got my email and he said he'd see if there was anything he can do, that is all I know at the moment. Figure I have that, the AW forums, and the feedback and president emails to try yet.
