Hi Vicky - I really would recommend taking your board out of the frame, as more and more people have or are upgrading to IE6 I have discovered.
I took my board out of my website frameset and simply have good clear links to my website pages. Actually I got one of the slideout menu scripts from dynamic drive.com and this really works well for me.
If you would like to see what I mean, come and have a look at my board.
The slideout menu is near the top of the screen on the left hand side.
P.S. This is not a plug for my board btw, I doubt there are very many bridge players here!
