It forces the browser to be closed to regain functionality.

I have the same problem here in IE (fine in Opera). It's caused by something in the "Find a Host - Webmaster Resources" pulldown. If I mouse over that bar IE will keep that error up until I ALT-CTRL-DEL to close the app.

Edit: typos

I've just tested the following on OS X and no errors: Safar, IE:Mac, Firefox.
Just tested firefox 1.5 on XP and no errors either!

I have the same problem. I use IE. It happens only on WHT when mouse goes over the banner. Not always though, but often enough that is becoming very annoying.

Hey mods - any progress on this issue?

...and it happens again.
