Keith,
Thanks for your note.
I don't know if your observations and mine are related, but both do seem
to be changes in program behavior ...
Is anyone currently using AB.ActiveWindow.ExportImage() with AB 5.30.4?
(Succussfully, or unsuccessfully)
Can anyone try the codes I posted, which are supposed to run as-is, and
report on what they observe?
