Windows 7 AIR systemChrome=none can't move maximized window

Steps to reproduce:

1. In Windows 7 click-drag in the title bar of a maximized window of an AIR application using a custom window title bar. (Note that when an application under Windows 7 is maximized there are normally 2 ways to un-maximize (restore) it: click the restore button, or click-drag the window title bar. The latter both moves and un-maximizes the window.)

Actual Results:

In our AIR application if we use systemChrome=standard in the app xml file, these 2 behaviors both work fine. If we use systemChrome=none, however, and use our own custom window title bar, maximize and restore buttons, it will un-maximize OK when clicking on our restore button, but dragging on our title bar area does not un-maximize nor move the window if it's in a maximized state. If the window is not maximized, dragging on our title bar moves the window fine.

Expected Results:

Dragging title bar of maximized window in Windows 7 should un-maximize (restore) window and move it.

Workaround (if any):

None
