I've got this senario: IE 8RC1 running on Windows XP. In 1 tab I'm on a website (say, channel 9). In a second tab, I'm on Windows Update. When I click the 'Install Updates' in the second tab, a download box appears showing the progress of the download and installation. However, I can not navigate back to the first tab while this box is still there.
Why can't I leave Windows Update running in one tab and continue my 'browsing experience' in another?
