I´ve crossed swords with Elvis previously on this forum but bottom line is that forums need people like Elvis who encourage debate and response . Keep up the good work Elvis !
Just hope that positive comments aren´t too disappointing for you!

it's entirely possible that something on the website is contributing to the required combination of circumstances to trigger the problem...doesn't mean there something wrong with the website. As i've said before this is a well known issue with FF. I've not been able to see this issue on 9 PCs in 6 different locations using 5 different browsers in each instance.

Always happy to look into problems with the site...it's not perfect. With so many browsers and PC configurations it's almost impossible to build a complex site which will not suffer some inconsistincies. We try to address as many as possible but it's not always possible. Also, i think that Mozilla probably have the same view as we do on this one, not been able to scroll with a mouse wheel on a web page is unlikely to make the top 10 bug fixes.
