Jerry, that simple tweak worked to improve the performance of the UI a
great deal...... its a slower method of loading...........but not too slow
to use as background loading. ...Its actually better than what I
expected.   Awesome.
I always love to use the forever loop..... its just so fun to write. lol
I gotta get some error handling in there but thats another story.
Consider this one SOLVED. Thanks again.
