Module Hangs on Close

I have a module that I created a long time ago, use quite often and published into our Plateau LMS. All of a sudden, it is now hanging when you click on the exit button (the windows close works fine). We have recently upgraded to Pro Suite v2008 (5045)The exit button on the page only has a Close Title on click. I have tried both inheriting it from the title and an individual button on the page. I have also tried copying a page from a module that works...all to no avail.Up until today, the module had not been changed since 12/07.I get a javascript:void(null) message in the status bar of my browser.Any ideas or suggestions would be greatly appreciated!
