Has anyone ever had an issue with variables of type “movieClip” not correctly referencing their intended movie clip??

For example: in \_root I have a movieClip called “chart1”. When coding inside the main time frame (\_root), I will say x = chart1.\_x

and it will return “undefined” ONLY SOMETIMES.

However if I say \_root.chart1 it always works.

What could keywords can I use to describe this bug? Am I only one that has come across this?
