Thanks to Mike Bonner for his helpful suggestions. Stack A and Stack B are both
mainStacks. Further tests seem to confirm this rule:
A setProp or getProp handler in the script of stack A cannot be invoked for a
target in Stack B UNLESS we have "started using" stack A (even if Stack A is
I have for years successfully run a set of stacks using LiveCode 5.5.3 in
Windows 7. Recently certain operations have become painfully slow (Windows
says "not responding" for 2 minutes or so, but eventually does respond and the
operation is completed).
Setting some breakpoints to investigate,
Is there a way of scripting the export of an animation constructed in Livecode
to some standard video file format (avi, mp4, etc.)?Alternatively, is there a
way of scripting the creation of a standalone Livecode file that contains the
animation?

I have encountered a bizarre problem that occurs in a somewhat complicated
context. I wonder if anyone has experienced anything similar.
In short: when I click a locked field on one occasion “the long id of the
target” returns the expected result; but when I click on it subsequently “the

Thanks to Bernd for the simplest solution to my practical problem. If we "go
to" Stack A "the selectedChunk" will mean "the selectedChunk in stack A". But,
as he notes, preservation of the prior selection depends on certain conditions
(more on this below).
One anomaly is that "the selecte

which is possible, I think I have not clearly enough explained my problem.

Thanks for this prudent advice. The case I am contemplating would involve a
user creating new substacks to hold content. While I can make sure each
substack created by my program gets a unique name, if a file created on one

Thanks to Scott Rossi and Richard Gaskin for their suggestions, which led me to
the problem (large block of data stored as a custom property of a substack).
While poking around, I noticed that many but not most controls and groups, when

Is there some way to diagnose what elements are causing this? I'd like to

scripts, etc., and

I am trying to set the numberFormat so that calculation is precise enough for

Testing for speed, I found that my July 29 function--the one that uses
lineDelimiter and itemDelimiter--is thwarted when two parens appear as
consecutive characters, and gives the wrong answer in that case. Sorry about
that.

Can I just confirm that there's no way to print high-quality

Create the field with fontsize 4 times what your want, take a snapshot, rotate,
