1. Oh yes ! Quite a strange bug I might add, seeing as it's the same "launcher" as Opera...

2. It's slow but at least it works ; Opera doesn't load much else than Gmail, it's good to have Calendar too and I was amazed to see Maps run on the 770 !

3. Oh yes !

4. Well, it half-works : you can open tabs, but don't try to close 'em :-)
