Correctly track open windows and check modality.

Now checks the topmost modal window instead of randomly checking
some of the windows for modality (PopupPanel consumes events causing
some preview handlers not to be called). Now also correctly tracks open
windows so that closed windows will not be included in the windowOrder
array
