------- Additional Comments from Alexey Proskuryakov <ap at nypop.com>
This seems to be a bug in Cocoa: [[NSApp currentEvent] window] is invalid.
Filed as <rdar://4634031>.

Looks like m_mouseDown doesn't need to be initialized to the current event here
anyway, so I made it initialize with zeros.

I don't see how to make a sensible layout test for this problem.
