Title: Solve "None Resource" bug #2251

This affects the "None Resource" in the BuySellTab. The button variable, which is a "Container" object in that case, did not capture the mouse click. Therefore the capture() function must be called for the "ImageButton" object, which is a child of the "Container" object.

I am not sure if it's necessary to check whether the Container has children.
