Paul...... this is the stuff that will make you nuts when you maintain a web site. I just randomly went through about 20 of your links and everything works perfectly except the car show photo galleries e.g. Day of Triumph, BMCNEPhoto.htm, Netphoto.htm, British Legends 2006, Valley of Sin etc. They all load fine in IE and load 3 full screens off to the right in Firefox 3.5. So it must be something with how you load a photo gallery to your site that Firefox 3.5 isn't liking. Just went and checked the laptop version and it's running 3.0.11 and has the same problem. Randall had no problem with 3.0.10 so I guess that's where the Firefox change was made.
