Splash Method of Saving Data

[Roger Guay]

I am so sorry for bring this up again, but I just can’t find relevant information. In the good ol days one could build Mac, Windows and Unix standalones apps using the splash screen method to open substacks thereby saving data in the substacks. This Doesn’t seem to work anymore! I see there is a lesson for saving Custom Properties using this method but I need to save other data like new graphics in the substack. Help please…

Thanks,

Roger
