Use Freeze Window to prevent the flicker.
For some reason the freeze window is not working either because I am changing layouts or because I am going back and forth between scripts.
I am under the impression that freeze window keeps the display as is no matter what I do until I say refresh window. Are there any situation that would invlidate this?.
If you have more than one window involved it won't freeze.
If you have more than one script with Freeze window.
Thus, you can get a flicker because script one used perform Script to call Script two and the first line of script two is freeze window...
Yes this explains it thank you.
