If only. Hmmm.
Pop-up dialog still pops up. And stays up, screen center.
Normally, as said, it's best to have that pop-up window show itself, just to be certain that a capture was indeed made. Then I click on "Save image but hide".
My normal setting is:
The Basics -->
Interface Options -->
After Capture Show -->
PopUp Choice Dialog
However, if I want to automatically inconspicuously make a capture, I don't want any pop-up. No interaction. Other than command line batch file executing. Please.
So, if there can be a way of over-riding, via command line, that would be ideal.
