>How can I prevent a user from opening an application a second time? Never had the problem before, but seems like it all of a sudden became a problem with one of my clients. I searched both the download files and other thread and never found the right keywords as I remember it coming up several times before. I've toyed around with creating a memory variable,then wiping it out when they exit, but not sure how to deal with a computer crash or system lockup.

The computer crash will only be a problem if you want to check for the same form in more than one application. Each instance of the application keeps its own copy of memory variables.
Commercial frameworks keep an array (in the case of VFX: an array property in the application object), listing all the currently-open forms. Perhaps this should be part of your strategy.
