Challenge with Git-Bash

Hello,
with my Windows 7 Git-Installation I get following challenge:
1)	Set GIT_EDITOR to editor of your choice
2)	With Windows7 let this editor run in admin-mode
	Goto .exe-file -> right mouse-click -> compatibility -> run program
as admin (I'm running a German version maybe English names are slightly
different)
3)	Make a git action like git add file
                             git commit
	from the git bash.
4)	Now following message appears:  sh.exe: ./"editor of your choice":
Bad file number
Everything is fine without Admin-Mode set for editor. In other words if you
get rid of step 2) step 4) doesn't appear instead the editor starts.
Due to other tasks my editor of choice has to run in this mode - stupid
enough.

Any chance to get around this problem? (No not taking a different editor, no not getting rid of admin mode :) )
