I'm still not sure about this one.

I've been reading about some users with continual errors. I think I'll wait for it to come down via MU at some point in the future. In the meantime I'll stick with FF at home and this obsolete IE6 in the office.

There's a new feature called "Compatibility View" which caused me some problems. I find it's better to enable it in Tools > Compatibility View Settings > Display all websites in Compatibility View. I think that by default it is not enabled and it causes problems with the display / layout of some sites.

Firefox is still my browser of choice.

TBH I only use IE7 for the Abbey bank - they don't accept FF3x as a valid browser yet.
