Gigapixel AI: Unexpected behaviour opening images dragged onto icon

If I drag an image onto the Gigapixel AI icon (or send an image to the executable), it opens but the ‘save image’ button does NOT show the save dialogue and instead OVERWRITES the source image with the enlarged version without warning, then the program immediately closes. Is this normal behaviour?
Win 10 Pro x64.

Yes, unfortunately when you open Gigapixel in that way it opens in plug-in mode (as do all the AI apps). You need to drag images onto the open app interface.
