updating progress to user during long handler

[Kay C Lan]

Strange.

If your mainstack handler is in preOpenStack have you tried it in
preOpenCard or vice versa?

Or try this kludge. Move your mainstack handler to 'openCard'. Change your
current preOpenStack/Card script to simply move the stack off screen,
that's it. At the end of your mainstack's new openCard handler, lockscreen,
move the mainstack to on screen, unlock screen.

Hopefully then at the end of the preOpenStack/Card script the screen will
unlock, your openCard handler will send your updateme handler and the
screen will update as you proceed.
