PreOpenCard happens after the stack window is drawn and before the card 
is drawn. PreOpenStack happens before the stack is displayed.

"Lock screen" should really be named "lock window". It does not prevent 
a redraw of the entire screen, it prevents a redraw of the contents of 
the window. I think the docs talk about that.

If you want to position a stack before it's shown, do it in 
preOpenStack. Then there's no reason to lock the screen since the window 
hasn't been drawn yet. Actually, there's no reason to lock the screen 
during any "pre-" handler provided the script is dealing with the 
appropriate level (stack, card, or background) because that's primarily 
what the "pre" events are there for.

Probably. I'm a little lost on exactly what the problem was though.
