Windows 7 (vista) Drag and Drop Problems (UAC related) 

--------------------------------------------------------------------------------

I can't seem to drag and drop a file from Windows Explorer with elevated
privileges to Notepad (or any other editor) with elevated privileges. Why
not? Both have elevated privileges, so it should work. (BTW, I can use the
right-click/sendTo method, and -- with a confirmation that it's OK -- it
works).

Seems like these are the symptoms:
1. from normal user Explorer :: to normal user Notepad :: works
2. from Runas Administrator Explorer :: to normal user Notepad :: works
3. from normal user Explorer :: to Runas Administrator Notepad :: correctly
shows "forbidden" drag-drop icon
4. from Runas Administrator Explorer :: to Runas Administrator Notepad ::
shows "forbidden" drag-drop icon.

I understand #3, but #4 makes no sense at all. When will this bug be fixed?
Maybe I'll have to turn off UAC so I can get some work done....
