Vizard exits full screen after 30 seconds

I have this script that's modeled after one of Vizard's samples. It launches in full screen. But consistently after 30 seconds it reduces down to about 75% of full screen. While it currently runs in boarder-less mode, when there were boarders, after it reduced in size, the icon for changing window size remained the same. So there was only the option to reduce it even further. From this point if I then clicked full screen, it would expand only out to the 75% mark and not fill my entire screen. I could not manually drag it beyond this point either. What's going on?!

C3 = W2,H,D-W
C4 = -W2,CL,D-W

C7 = W2,CL,D-W

Are you running a trial or Lite version of Vizard? If so, it will only run in full screen mode for a limited time.

If your vizard is the FULL VERSION you can try the function below:

viz.go(viz.FULLSCREEN)
