Yep, looks fine in IE7 now too.
For what it's worth, I'm doing all this testing on my Mac. You can either load Windows on your Mac with Bootcamp (which comes with the Mac) or use a "virtual machine" program like VMWare Fusion (which I use) or Parallels. It's really nice to be able to use Windows and Mac all at once. I have IE open just like any other program.
A free alternative to Fusion and Parallels is VirtualBox. Either way, you still need to acquire a copy of Windows.
