Rollover Images not working on product page when HoverBox3 is turned ON

Hi Guys,

Have spent the last 2 weeks customising my first Zen Cart.

I have rollover images contribution working on pages where HoverBox3 isn't utilized, however the roll over images do not work on the product page where HoverBox3 is utilized... when i turn HoverBox3 OFF under admin, rollovers work.

I've spent the last 2-3 hours diging through previous threads and can not find anyone else with this problem, so i'm guessing it is something straight forward. Any help would be much appreciated.

Cart in question:

Note: use the header buttons as the reference, other various buttons on the pages do not have the _over images created as yet.

seems the images are getting the 'rollover' class attached to them, but its not working when hoverbox3 is enabled... so i'm guess it is a javascript issue? I've tried everything i can think of - starting to drive me nuts...

any help would be greatly appreciated
