outlook resides in a separate box on the taskbar...the other iterations of IE are all stacked in their own pile. I just click on the pile...all the titles are there, I pick the one I want to go to. No problem, just like tabbed browsing. I've been using it this way since day 1 and it works prefectly fine for me :)
Maybe I am an abberation, but I'm a happy one using IE6 .. and i rarely have a crash with it...less than rarely, actually. Maybe I'm an exception, but as long as it works, I'm aok.
I used to be the first on the block to download and use new software, especially intenet browsers and all that. I've done tons of beta work.  I've now found a product I enjoy using and don't need the new, better???? products. It seems every time i try a new thing, I'm just not happy using it, so its time to just stick with what I like to use.
Its like that with a lot of Poser users too..they're still using P4 or with pro pack, and perfectly content and happy with it. Sometimes the new bells and whistles just don't fit with everybody.
