That is true.  However, just adding the single command "lock screen" before the 
"go card xyz" removes the problem.  I have tried to understand what could be 
"illegal" in the target device point of view in the script code following, but 
so far haven't figured it out.  Actually the script runs until the end, and 
does not exit.  The process this happens is rescaling all the cars of the 
stack, from figuring out the screenRect and then calculating how everything 
would fit on the virtual paper in the optimal way.  If the script is allowed to 
run without locking the screen, filling the background and fields is completed 
only partially, but simultaneously setting the loc seems to work ok.

What I observe is that the colouring of the background & the fill of those 
objects stops randomly as the next object size setting starts.  I do hope I 
will find out a typo, which could be referring to another object - but why then 
lock screen or wait for x milliSeconds would remove the problem?

When you say exit to the top, wouldn't it mean that the stack script execution 


I've seen this happen when something goes wrong in the code and in a standalone 
that can fail silently. If it does, the engine exits to top and that is why 
things get left undone.
