The moderators can't "give you a solution". This is a peer-to-peer forum.
The only think I can think of: poll the "running" applications list periodically. If a "blocked" application is running and has the focus, pop a global-modal dialog that says "restricted application" or something like that. Do not allow the user to dismiss the dialog. The dialog will come up over the top of whatever screen the application is showing.
