Hi Steve
Yes I know of the firefox problem, it worked fine up until a few week ago, when I updated the CMS, I changed from Mambo to Joomal and it all went Tits up.
I'm woking on a new template as we speak, I actually prefer Firefox, because it is less forgiving that IE, which makes for better pages.
It's going to be a while, as I have to work for a living:( and the CB750 re-build it steaming along now.
