I found out about MyIE2 in some other thread here and I gotta say this software simply rocks! For everyone that ever wanted tabbed browsing and some sweet features such as simpler navigations, great favorites management, better RAM mgmt etc... this is the software. It's pretty much like Firefox & Opera except it's a 'wrap' around IE6. So obviously pages are rendered exactly the same.
This my sound like spam but the soft is free

Just started using it yesterday and I can't get enough of it.
(Google bar works but there's a little trick needed to get the PR of a page :-/ )
