Well now that makes a lot of sense! However, here's what's traced:
parent_container.x: 100
parent_container.y: 208
displayObject.x: -75
displayObject.y: -75
and the object doesn't show up. I've been playing with values for the x and
y of displayObject but with no satisfactory results. Just to be on the safe
side, the code follows. Please advise once again.
TIA,
