[Closed] Need test about when handler issue

hi guys,
need some help testing a little script.
I’m getting unexpected behavior and don’t know if it’s just because of the version.
currently using a old version of max (max 8)

Execute, Push the “context” button and move the box around
Normally the second Point should stay where it is even if it’s his child

When I translate only X axis is realtime, when moving in Y or Z redraw happen only when I move another time
Same behavior with rotating!

thanks if you can test and give me feedback and you’re max version
