MSN Tabbed browsing toolbar again

If you’re thinking about installing the MSN toolbar with tabbed browsing for MSIE, forget it.
It’s incredibly instable; since I installed it, my Outlook crashes on each and every operation with an email. You can imagine how very, very frustrating that is.
In addition to that, the switching between tabs in the browser starts a firework of weirdest window switches and blinks. I do understand why it’s so difficult to add this functionality in an already existing browser, but this solution is simply not worth the effort.
I’m uninstalling this ‘thing’ right now.
Sorry Microsoft, nice try but not there yet. Back to the drawing board.
