In response to below------Thank you Lynn-----Yes, there is a main panel--I will attach----and if you have any further suggestions please let me know--Thanks again
How are you running this program? Is there a top level vi which calls the ones you posted? The Display image on screen.vi will display two images in succession, but according to the note on the block diagram the second image is blank. It seems as though this would intentionally create a flicker.
The sequence structure is unnecessary. Dataflow will determine the order of execution. The only exception is the time delay in the third frame. Since it has no data dependency, a single frame sequence may be useful to assure that the delay occurs before the picture is updated. A simple state machine might be a more versatile architecture for what you may be trying to do.
It is not necessary to write the FR.PanelBounds property immediately after reading it, nor is it necessary to read it a second time in the second frame. Just wire from the first read.
