I just upgraded to WP 2.6.5 and I met the following problem.
On the Widget page I am no longer able to change the order of the activated Widgets (right hand side) with drag & drop.
The problem is present at firefox AND IE7.
Does anybody know a fix for this problem?
All the best
P.S: I am using K2 and there the advanced navigation (search without the need of hitting a go button no longer works).
