Your picture does not show an invoke node or a red area at all.  Can you please clarify your question?

Hi roverboy,

do you have another control/indicator with name "Image"? I think it´s an invoke node, right click on your control/indicator and select -> create invoke node -> Get Last Event.

Hope it helps.
