I've heard this, but I've also heard the performance is better.
What platform/configuration are you using?
Windows 7, I don’t have any special add-ons running in the background other than the usual Flash. Something else I just noticed. It doesn’t seem to like Adobe Acrobat Pro. In other browsers, if you click a .pdf link, it will open in Acrobat Pro. With version 4, it doesn’t recognize Pro as a replacement for Adobe Reader and just gives an error message.
Better for all 3 machines we’ve updated. All running XP SP3, 2 of them fairly sturdy beasts with 2 GB RAM, another an ancient clunker with 512 MB. No crashes, notedly faster.
I’ll update the Vista box soon also, but for now I have one addon that hasn’t been updated and I’d like to keep it around til it is.
