A few minutes ago, my Fedora 11 box asked if it could install 11 updates (and it listed updates to Firefox and other browsers). I said OK. Then the little red indicator appeared. Hover over it; take a screen-shot:
It’s in the middle of more calculations at the moment, so I’ll wait 30 minutes or so until I can interrupt it. Then restart Fedora. Then resume the calculations.
That’s how a sane OS behaves.
