Sounds an odd one that. Possibly to do with 'Mandatory Integrity
Control'.....
A couple of articles that may help .....
Mandatory Integrity Control

Mandatory Integrity Control

SysInternals also do a tool with which you can view the integrity level of
an object
AccessChk v4.02
http://www.microsoft.com/technet/sys...AccessChk.mspx
To give a simple example - create a file on your desktop eg test.txt, and
then open up IE in protected mode. Go to the file menu in IE and browse to
the file, and try and right-click > Delete. You'll notice that you'll get a
whole load of prompts to delete the file (or possibly not depending on UAC
settings), whereas if you close IE and just try deleting it from the
desktop, it will delete with no problem. This is due to IE running with low
integrity, which also protects you while you're surfing the net.
Perhaps something similar is occurring in your case (?).
