Using Md5Digest on stacks loaded in memory

Hi Dar,

Thanks a lot for answering this question.

But, it's possible to get a md5digest of a custom
property that only exist in memory, because
the stack has not been saved to disk yet.

So it could exist some way to get the md5digest
from a stack that exist only in memory 
(and still has not been saved to disk). 

I believe that the engine uses a md5digest of 
the stack to ask the user if wants to save 
the stack loaded in memory before closing it.

Yes, i suspect that. But the purpose of having
a digest attached to the file is to reduce the
risk of having a substack that execute scripts 
not authorized on the machine that is running.

I know about the secure mode, but it is a major
blocker. The stack could not write a text file
to disk or change the registry (all these 
restrictions are fine), but when i try to put 
text in the clipboard, to paste in another document
the clipboard is always empty!?!?!?. 
I've tried this code, and many variations 
without success:

set the clipboarddata to localVariableZXC

I'll like to be wrong about this, and that even in 
secure mode, i could put data on the clipboard to 
paste in a text editor, like notepad, but in my
side this is not possible or maybe i'm using the 
wrong code.

Looks like this is the solution, but this question
still remains unanswered: 

How could the engine get the md5digest of a 
single part of a stack loaded in memory 
(a custom property) and not from the whole 
stack, that only exists in memory too????
