C# windows form using user32.dll functions not working as non admin user

I need some assistance with a windows application that essentially opens some files from a list the first time you double click the items/file. The second time it enumerates all open windows and if there is a window open with this filename then push it to the front. This does not work as an admin. C# 1.1 What priviliges should the user have or what code should I put in to make it work? The code posted is not all the code but only the releval part. This code is simple to test though with a small windows form app. Regards Ken ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
