I am having serious layout problems with my tours when viewed in Firefox v. 3.03 on Vista SP1. In some cases the navigation bar for my thumbnails is completely missing. This is a major problem and I have not been able to find any information on this yet. I do business in a college town where the college promotes the use of Firefox. According to CPanel about half of my visitors are using it, so any help in resolving the problem will be really appreciated!
