hello. i've been working on a website and everything works/looks fine except when viewing the site with firefox on a mac... one of the pages has two frames that should work at the same time when a link is clicked on the page. however neither appear. i have another page which has only one frame and it is working fine. so i'm thinking there must be something in my code which is making it impossible for the two frames to work smoothly in firefox. i hope this makes sense... here is the problem page (with two frames, one to the left of the links and one above the links): and this page works fine (with one frame to the left of the links): if anyone can shed some light i'd really appreciate it, thankyou.
