Sometimes, it's clear what minimum window size they've assumed. I know of one (bank login) which doesn't work well on a netbook due to this. I tried to report the problem via the site feedback link which they helpfully provide in most of their page footers. It fails in Firefox but works fine in Chromium; I ended up reporting two problems reported instead of one.
