quick display question
 

I am using the trial version as of now and after the program runs for a while the window size reduces from the size I originally set it to be. Is this something that the trial version does but not the liscence, and if not how can I fix it?

The Trial/Lite versions of Vizard only allow fullscreen mode for 10 seconds, then automatically shrink to windowed mode. The Development/Enterprise versions do not have this restriction.
