Quote - Those aren't really errors because Renderosity use stylesheet declarations which are only supported by IE and so FF drops them.
This happens on a lot of websites that don't use only standard CSS declarations.

So AIUI, the problem people where having was due to a change of style on mouseover / hover.

Sounds that way nruddock.  Thank you sooo much for your help. I just love when I see you jump in a thread cause you are always so very helpful.
