Visual Studio 2005 + Vista = Annoying

I’ve recently upgraded to vista on my laptop at work and am getting increasingly annoyed by one ‘broken’ aspect. Why can I no longer drag files from an explorer window into a ‘Solution Explorer’ in VS?

I’m assuming it’s something to do with them running as slightly different users as I have to run VS ‘as administrator’, well that’s what MS advises anyway.

I do hope this is fixed soon!
