I got another toughy. I can't get the auto centering to work inside a scroll box. Not sure if this is intended behavior or just a bug. Here's the "Set Auto Centering" Scripting Index example modified to include a Scroll Box. You can see that the auto centering/streching no longer works for objects inside the Scroll Box. If anyone has a suggestion or work around I'd appreciate it.
