I've got an application sitting on a Citrix box where I want to prevent the user from being able to right-click within a common dialog box and getting the menu of delete/copy/ etc etc. I've got privileges set so the can't delete from dangerous folders (like c:\windows), but I can't set stuff up so that they can't do a file copy from inside the dialog box.

Basically (ugh) I want to TOTALLY inhibit the right-mouse within the box.
