Vertical scrollbar not appearing in some browsers

IE on XP, Beta 1 grid. This also has the effect of not being able to select a row, in fact trying to do so deletes the row. Beta 2 in said browsers is even worse, the grid never paints at all and there is a script error pointing back to aw.js.

I think that you have some configuration issues. I develope exclusively on XP using IE 6.0 and have never seen the issues you speak of. IE on XP is the most common configuration out there and you seem to be the only one reporting this bug. Check your IE settings to make sure that you have all your JavaScript settings correct and that your paths are correct. Have you tried to run the demo pages that Alex has on this web site from your OS/browser combination to see if they work? If they do and you can not get your own pages working then you have an issue with the way you are calling the AW.JS file (wrong path, wrong version, something).
