Yep! I've been thru something like this too, the difference here that  
springs to mind is that the book you are talking about was written by  
a third party, whereas the problem here is with the makers of the  

The thing is that there are loads of example stacks and examples in  
the documentation that use the form:

put <something> into me

IMO, they should *all* be changed so that they work 100% of the time  
or at least a footnote given stating that it will only work *some* of  
the time!

I'm in the process of changing all my scripts now! I just realized  
that a bug I had in a completely different stack was due to this. I  
worked around the problem another way (using the "openCard" handler  
to re-initialize the objects in question).

Just so I understand this:

in some circumstances; put <something> into me

Result in the object contents being used instead of the reference to  
the object? If this is true, then if the field just happened to  
contain "button 1", would:

put "XXXXX" into me

result in the contents of button 1 being changed?

Thanks a lot
