>>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.

>>Any help appreciated
