This goes back to the padding problem and the fix that I employed.
All works well with triggers by process filename except for Paint.net.
When a save dialog is created and the output is a .jpg, a second screen is created and the trigger is activated for this second save setting screen - Not desirable.

The goal - fix the main window only (first window created).

One way is to activate the trigger via window text.
The default text is "Untitled - paint.net 4.2.15"
The 'Untitled' component can change so therefore disregard, and 'paint.net 4.2.15' can be picked up by a zip folder name/or executable installer.

Here is the problem:
" paint.net" (space preceding) is not triggered - this would be a very accurate means of detection as zip/installer would not have preceding space

"- paint.net" is not triggered

"paint.net " is triggered but still could have false triggers (zip/installer)

Why are the cases that are not triggered problematic?
