Site critique please

[annc]

I'm redoing a site that I first designed many years ago, and have the design and content of the home page ready for critique. It validates with the W3C, gets a 100 score on sitening and displays as expected in Safari and Firefox on the Mac, and in Firefox, Opera and Mozilla on my Windows box.

But in IE6 (of course) there are a couple of problems. For a start, the right-hand column of pics sits up into the top banner; also, if I narrow the window, the entire centre column jumps down below the left-hand menu; and the flyout menu (hover over Events to see this) is in small text. It is the same size as the main menu in all other browsers.

I'm sure I knew once how to stop the centre column sliding down in IE6, but can't remember how. The other problems in IE are a mystery to me.

Any critical comments and advice welcome.
