Microsoft released a new beta of IE7 on Match 20th, which seems to resolve many (but not all) display glitches that the older beta had.

Also, the rich text editor support seems to be better and faster.

I still wouldn't recommend that regular web surfers install it, because it is still a work in progress, and many websites do not work properly with it yet.

However, website developers should probably get it at this point, because there are changes that will be required to websites in order to support the new browser.

For example, CSS hacks that are programmed into a site to get around IE5 and IE6 bugs will need to be addressed, so that they aren't used by IE7.  Lottery Post has a few of those that I'll eventually have to iron out.  It's a pretty big task.
