--- Comment #5 from Dan Kegel dank@kegel.com 2010-04-11 20:30:10 --- Yes, I'm using the same version as you. For some reason, I'm seeing this problem on my i7 at home, but not on the gentoo box at work.
I've seen references to other people not seeing the license agreement in appdb, too.
(Incidentally, when builtin ie6 does work, I get a bunch of empty messageboxes during the starcraft 2 autoupdate. That's another problem worked around by native ie6.)
