I read your question and checked its progress on the StackOverflow (SO)site.
Given the higher activity and the type of users at SO, your question will probably fare better over there. I recently had a question that could have gone in the Webmasters site, but I posted it in SO instead because I wanted a larger audience.
Your question had more development (MSO development) specifics than is normally discussed on the Webmasters site, plus, it had the added detail on Windows7 clients.
I see your point, and also, given the recent splintering out of some of the subject matters this is potentially a recurring theme. For example, there will be much overlap between StackOverflow and the UI site as well as Webmasters and the UI site.
With growth comes a little pain, I suppose. :-)
