Very interesting point Jacqueline. In my case my image control displays nothing. I use it as a template, ultimately to make images out of what users drag and drops. It's the same dimensions as the stack itself. Since the image control displays nothing as it isn't linked (the FileName of it) to any file I'm not sure whether the whole thing is consider transparent pixels or not. Livecode doesn't seem to have a setting of transparent or opaque for image controls. So I've experimented with buttons giving them the same script as the image has:
on dragEnter set the dragAction to "copy" pass dragEnter end dragEnter The new thing I've discovered is I can consistently break Livecode's accepting the drop, evidenced by the cursor turning into a circle with a line through it instead of a plus sign, if I drag extremely slowly right at the point where I stop dragging across the desktop and start dragging over the stack window. This happens even if I let the button overlap off the stack window. If I continue dragging around on top of the stack to another button with the same script I do get the plus sign for a cursor.
