Problem with Buttons

I have built a template for our training and everything works in the preview mode. Once I upload it to the training site, the exit button stops working.It has been assigned the on click exit title/close window command, but all that happens is that the window freezes. The button also disappears at this point and "the little red x" appears. At this point, if I roll over any other button, they also disappear and are replaced by "the little red x".I am using Lectora v2008 SP2 on a Citrix system.Any help much appreciated.CheersLance.Additional: This is only occurring with the "Exit" button. "Next", "Back" and "Home" buttons all work as intended.Edited By: lancetre on 2009-1-5 17:6:57
