More about image timing

[Brian Yennie]

If this is truly just a lock screen issue, wouldn't it stand to  
reason that the Rev IDE is slower because it has a lot more stacks  
open and affected? Or am I missing a crucial piece here?

It would seem that having a bunch of extra stacks open (and in some  
cases visible, including the toolbar) could easily add 1 millisecond  
to every 10 loops of a screen altering script...?
