Checkbox in Grid Header cannot be clicked

Hey Alex, your product is amazing! I am VERY happy to see that you are now offering support for other browsers as well.

A small bug I've run into with version 2.5 (Alpha 2):

I have checkboxes in the header of my grid. The checkboxes can be checked in version 2.0.2, but not in 2.5. When I click them, nothing happens.

Any advice?

This is a bug - will be fixed in the next cut. Thanks!
