right click in listgrid headers does not work in 11-8-2011 nightly

[Sytematic]

Hello,

In the Power Nightly of 11-8-2011 (2.5) in both Chrome and FF7 (Mac OS X) i cannot right click to see the context menu anymore in a listgrid header. i can using the little arrow image, but then all items like sort and group in the context menu don't work. Clicking it just discards the context menu, not doing anything.

Could you look into this?

It also goes wrong in the drop down menu in the Developer Console where u can adjust logging.

Overnight regression, already fixed for tonight's build.
