Windows Permissions?

Technically yes.  Though it's not encountered as often because Windows 
allows the user (changed now in Vista) to install as the admin and then do 
everything at admin level without question.  However in environments where 
the admin is not running you'll meet this issue.  The inconsistency causes 
confusion.

Could also be caused by having the app running still but visible only in 
Task Manager.
