So, first three minutes with IE9, and my thoughts are:
- The new interface looks spiffy.
- Cufon is broken in IE9, so my site looks terrible.
- What kind of idiot thought it would be a good idea to make an undifferientiated part of the clear area at the top of the browser launch new tabs instead of maximizing the window on double click?
Double-clicking in the portion of the top of the window where the tab bar would extend to causes a new tab to appear instead of maximizing the window. There is no visual differientiaton to indicate where the cutoff point between these two behaviors is located. Thats a usability fail right there.
