- One machine had both browser installed after IE7, which it shouldn't have, but did not import Favourites from old browser
- Another machine got a version of IE7 that keeps crashing all the time
Another thing is, that if you do nothing, Microsoft will simply force IE7 onto you by putting it out af a high-priority "security upgrade" through Windows Update. That sucks! Fortunately, a toolkit - actually released by Microsoft - will allow you to block that particular update.
Installed the toolkit, and will now go directly to installing the new Firefox 2.0 :-)
