I have a Motif application that is unusable with Motif 2.3.2 apparently because of a change in the behaviour of paned windows.

The code below demonstrates a much cutdown version of the problem: it creates two label widgets as children of a paned window. With Motif 2.3.1 both labels get a fair share of the paned window; with Motif 2.3.2, the program starts up with only the first label and the "sash" between the windows visible.

In the real application this is a stopper: the paned window is part of the applications main window and its top pane is an information bar with a fixed height while its bottom pane is a multiline text widget. The text widget is now inaccessible as a result of the changed behaviour in 2.3.2.

Regards,

Rob
