Bit of a weird one this, as I've not seen anyone else mention it. All of the post beta builds have had a bit of a weird effect on my Start Menu. Sometimes my Star Menu will stop fully expanding (not all the time, although once it happens, I have to reboot). This happens on both my main machine and laptop. At first I thought it was because I was just doing upgrades, but for the RC I did a clean install on both, and it still happens. It's annoying as I can't get the the All Programs bit and launch things! I do have my computer set to display large text and I've set the font myself too to make it more readable (my eyesight's not wonderful), so I'm not ot sure if this, coupled with them both being widescreen displays (lower height) is the cause, or if it's something else. This is a bug Microsoft do need to remove, as I'm sure there are quite a few people who set up their computer like mine for accessibility reasons, and so this may be a problem when it get fully released. However if anyone knows a quick fix, I;d be eternally grateful (obviously not soemthign along the lines of reduce the text size, as there's no point in fixing the start menu if I then can't use the computer at all).
Here's a screenshot of it (first pic I;ve posted, so here's hoping it goes well):
