I've got a site that has a menu bar that contains buttons to launch a few apps. When the user clicks on the first button, lets call it App1 it opens a new Asp page (lets call it App1.asp) in a new window. If after that the user goes and navigates somewhere else in the site and presses the App1 button again it doesn't know that it is still open. All i want to do is check to see if App1.asp is open, and if it is bring it to the foreground, set focus to it. Is the some sort of a Script function that i can use?
