Just a thought -- would using fromTo with labels at the start and end of the tween achieve the same result, i.e:
TweenMax.fromTo(MC_Anim, 3, {frameLabel:"move_start"}, {frameLabel:"move_end",ease:Linear.easeNone});
...seemed to work for me
Galbraith,
Thanks for your code - it worked perfectly...
I'd like to add one point that might save others hours of troubleshooting (unless I'm the only one who would miss this)
UNCHECK THE FOLLOWING: "Center X" "Center Y" in the Gaia Project Panel
Not doing so resulted in my pinned liquidstage objects flying off the screen when I resized.
Like Galbraith shows there is no need for global static variables so you can use his code verbatim.
