Unable to drag folder into Mp3Tag in Win7 x64?

Hello, searched for this on the forums but may have missed it.

I have Win7 RC x64 version and it appears to have lost the ability to drag a folder of music into the editing window. This worked fine in Vista x64. I've tried installing Mp3Tag as admin and running it as admin along with setting compatibility settings to Vista SP2 to no avail.

UAC also barks when I try to run it, is that because it's unsigned? Thanks -

Are you always running Mp3tag as an admin? If yes, does it work if you run Mp3tag as normal user or Explorer as admin? You cannot drag an drop files if the two applications do not run as the same user.
