AppleWin: screenshots?

On my Win11/64 laptop, at startup, AppleWin complains that it can't trap the PrintScreen key.  I believe it's because I have Greenshot installed on it.  I don't use it but may eventually find use for it. It doesn't do this on a Win7/64 laptop at my day program.  I tried the key there and didn't see anything.  I don't know if it did it silently or ignored the press.  I'd better check the game's folder, as it was on a flash drive.
