You might want to turn off ‘Multi-window browsers’ and ‘Reuse windos’ in ‘browsing too. Drives me nuts.
Wow, that Multi-window browsers option is UI-evil incarnate! I really don't understand why people just LOVE _modal_ UI's and modal browsing. :) Modal browsing is so cumbersome and impossible to follow anything.
Just curious why don't you like Reuse Windows? That saves me from accidentally accumulating 15 windows opened on the same class, without stopping me from easily duplicating a window if I need to..
