[7.5] Changing looks causes windows to collapse randomly

During the process of changing look preferences collapse events are being triggered by the OS.

(Please refer to the stack trace below, taken during the course of changing look preferences).

 

This causes the window's iconic variable to be set to true.

 

Subsequently when the Window is reinstalled (finishOpening) and mapped during the look change it gets mapped as an icon, thus collapsing the window.

 

See

ApplicationWindow(Window)>>map

                       

primMap

            If an unmapped, collapsed window is mapped, it will be mapped as an icon

            (if icons are supported by the platform window manager)."

 

Does anyone have any suggestions as to how to prevent this random behaviour?

 

Cheers,

 

Stewart
