I have several questions regarding the use of  Fourth Dimension.

First, however, is this the best BB for this topic?

Question 1:  I want to use external procedures.  Does one absolutelty
need to purchase the 4D externals package to do this, or can one simply
place an XFCN type code resource into the resource fork of 4D and
then call it by name from within 4D?

Question 2:  I want to use scrollable boxes as an input device 
for the construction of queries.  This contrasts with their usual use as
a data entry mechanism.  Ideally, I would like to be able to multiple
select in the scrollable objects but so far can only single select:  I
don't think this is possible.  Is it?  
	
	Another problem that I am having with the scrollable objects is that
they are inactive when the layout first comes up.  I have to manually
select "add new record" from a menu in order to activate the objects.  
I discovered this empirically and I have some theories as to what is
going on (that the boxes can only be used for data entry) but would
appreciate an explanation and a solution.
