Ok, I've tried to fix this myself and am at a loss again, so just this last thing or two I swear and I'll let you guys alone, promise!

I assume the lightbox I use for the galleries is being messed with by the menu code. Ever since I fixed and validated all the pages, when you click on a gallery thumbnail it still works but sometimes it jumps all the way to the bottom of the page. The lower on the page the thumbnail, the further it jumps.

The other thing seems to be that the menu is cutting off for some people, something about overflow. The one who told me about this is using a laptop, I don't know if that has something to do with it or not.
