Joystick Gremlin: Mapping Screenshot (Windows Key + PrtScrn) to a Button

Hi all!

First of all - big shout out to the creators of Joystick Gremlin and vJoy - they are is truly awesome! I have a sophisticated profile for a HOTAS Warthog and it’s amazing.

But i’m trying to map a button to do a windows screenshot for use in MSFS2020, by pressing windows key+prtscrn. I’ve tried map to keyboard, and a macro that I think handles the right sequence of press and release. But it doesn’t seem to work. I’ve verified the button press with the viewer, and I’ve added extra simply keypresses and they appear in notepad when I hit the button. But the print screen with windows key doesn’t happen.

Am I missing something? I think I don’t understand something about how modifier keys are handled.

I see there was a topic on this on Jan 1 but was cancelled after no replies!
