I'm perceptibly a bit late to this post, but that's only because I recently learned that this community existed at all.
Anyway, I use Acrobat Pro but I'm not sure of what "visually digitally sign" is unless it has to do with that stamp/signature pane. I am inexperienced with ControlClick
, though, so I don't think I could be of much help to you there.
coordinates change with window resizing or different resolution displays.
So set dynamic coordinates for every single possible window. If you're using AHK to resize, then I would imagine it would only be to a few specific windows at most, and you could link the sizes to their own unique coords each time.
