Hi all!

I've been using the "recipe" for "rolling credits" (provided in the docs) for the main text field in a "Help" stack I'm putting together for the application I've been working on.

Works great - and everyone who sees it agrees that it's a real nice touch. You click once on the field and the text scrolls to the end, and then resets.

However, I got to thinking, since this is a help stack, my user might want to click on the field at some point to stop the scrolling, look at something for a while, then click again, to have the scrolling pick up again at the same point.

My first thought was that it should be easy to modify the original recipe to get this effect. And maybe it is. But, after a few frustrating hours of no joy, I thought "Hey! Asking for help is no shame", even though I strongly suspect this has a very simple answer.

So, I'm asking for help - humbly, I might add.

Here's the script from the original recipe (so you won't have to look it up).
------
local maxScroll
constant scrollIncrement = 1
constant frameTime = 25


on startRolling -- begin rolling credits
  put the formattedHeight of me - the height of me \
     - the topMargin of me - the bottomMargin of me \
     into maxScroll -- the most this field can scroll
  send "rollCredits" to me -- triggers the first frame
end startRolling

on rollCredits -- rolls the next bit
  set the vScroll of me to (the scroll of me + scrollIncrement)
  if the vScroll of me < maxScroll then
    -- trigger the next frame:
    send "rollCredits" to me in frameTime milliseconds
  else -- we're done:
    wait for 2 seconds -- to let the user read the last part
    hide me with visual effect dissolve
    set the vScroll of me to zero
    show me with visual effect dissolve
  end if
end rollCredits

Thanks in advance,
Alan Gayne
