can't drag and drop font groups in vista 64

This worked fine under xp (32 and 64 bit), but now with vista business 64, the cursor just turns to a no symbol when I try to drag a folder from the network onto the maintype groups window. does not matter if maintype is running elevated or not.

Please advise! Thanks.

MainType is always running “elevated”. At least if you are running the latest version. Please correct me if I’m wrong.
