Lummox JR	Does this apply only to /image objects or do regular overlays have the same issue?

SuperAntx	I went and tested it, seems to be overlays in general having the issue rather than just /image objects.

Lummox JR	Okay, good to know. That makes sense to me. It's probably an issue with the hit test itself. I'm not entirely sure this counts as a bug because mouse_opacity=1 on the first icon hit should mean that icon gets the mouse hit, but I'll look at this in more detail to be sure.

SuperAntx	Hmm, I guess you're right about that. Perhaps mouse_opacity needs a third setting where that object is hit regardless of what else is occupying the same location.
