Well, one thing that immediately pops to mind is the fact that now I've got to clutter up my form with text, explaining to the users that if they wish to view in full screen mode, they should press F12 and to return to normal screen mode, press F12 again. This is hardly the way to go. Surely, Preview by default should open up in full screen mode or at least have a 'View Full Screen' button alongside Preview???? Some users are bound to press F12 and get into Full Screen Mode and then forget how to get back again?? We're dealing with all sorts of visitors you know, both young and old and intelligent and dim and the developers aim is to make life easy. That's probably why eBay preview in a window! Nick.
