I am just playing with DOM to create dynamic galleries from a static list of thumbs and got a really odd problem in firefox: http://www.icant.co.uk/articles/dyngallery/index2.html If you click on one of the thumbs you get to the sequential viewer, clicking the lower image gets you to the next one and the upper one to the previous three. However, when you are on the second or third (not the first thumbs) and you click the upper one to go backward in the gallery, firefox looses the margin in between the divs. Does anyone know why that happens?
