Think I might have sussed this one, though I'll need to do more
investigating.
I create the main window, then load the window co-ordinates from a file.
(The window position is saved so that the window appears in the same
position, the next time the script runs). I invoke the Change method to set
the window co-ordinates. The Change method must generate a window-resize
event. In the Resize event handler, I refer to a control which has not yet
been created. The reason I did it this way, was so that controls could be
sized relative to the their window. Looks like I'll have to think about just
putting the controls on the window then calling the Change method last.
Ian.
