Scrollbar causing resize problem

Ok guys, this is killing me. I can’t figure out what is going on and ive been smashing my head against it for weeks.

I am using snickelfritz’s code for a dynamic text scrollbar from here actionscript.org/forums/showthread.php3?t=179870.

when the scrollbar isn’t triggered (text not bigger than box) everything is fine and my liquid layout works. But the minute the scrollbar is triggered the page suddenly jumps to a fraction of its normal size. I don’t know how to work around this but maintain Snickelfritz’s code. I feel it might be some problem with tweenmax?

my in-progress swf is: calsoc.org/CS4.swf
and my fla can be found here: calsoc.org/CS4.fla

thanks, I really appreciate the help
