Gmail does not load on IE8

I have an email with Google Apps for Domains. It loads fine in every other other browser, but not IE8. First it will sit there with the non-moving progress bar, saying Loading blah@blah.com.

Then after about 30 second or so, it'll say:

Loading standard view | Load basic
HTML (for slow connections) This is
taking longer than usual. Try
reloading the page.

If that doesn't work, you can: Try
using https. Disable Labs and try
again. If you're on a slow
connection, try basic HTML view. For
more troubleshooting tips, visit the
help center.

I'll click on the Try reloading the page link, which is the exactly the same URL that went to to begin with and it'll load just fine.

I've tried clearing cache, cookies, disabling all labs – nothing helped.
