There's a dontRefresh property for videoClips that will cause the last
frame of the videoClip to be grabbed when the clip ends. As long as
you don't change any of the controls in the area where the videoClip
played, refreshes won't erase the last frame of the movie. If you're
playing a videoClip directly from disk, you must set the dontRefresh
property of the templateVideoclip to do this.

If you need the frame to be more permanent, take a snapshot of the
last frame of the clip and then hide the image and show it again just
before starting the videoClip.

You might also consider using the offset() or lineOffset() functions
instead of using find to find text. You may need to set the "scroll"
property of the field if you want the found text to be scrolled into
view (you can computed the scroll property using the lineOffset
function on the formattedText of the field multiplied by the effective
textHeight of the field).

Redraws in 2.0 are confined to dirty areas even when using lock and
unlock screen, so you should have somewhat less trouble with the last
frame getting whacked with 2.0.
