Thanks for the response. I suspect that security had something to do with it. But the randomly visible folders is really strange not sure why that is security related though.

First you should not be writing to "Program Files", you should be using the current users or the all users directory.  For non-vista apps all access to the program files directories will be virtualized.  Any writes there will be redirected to a folder under USER\AppData , I don't recall exactly were.  All reads will first look in that location and then in the actual location.  There is an option in explorer to display a unified view of the file system so that you can see both sets of files.

In case you didn't know, even when running as admin on vista only programs explicitly marked as needing admin privileges will be given them.  All other programs will run with normal user level privileges.

Hope this helps.
