Bill,
I don't see anything in the handler that should require a wait, if
that's all that is going on. Is the map still loading while you're
trying to get the snapshot? Any pending messages? Even so it doesn't
make sense, because once a handler triggers it should run to completion.
Normally any pending messages will be suspended until the handler
finishes, but the waits in this one will allow them to process. Then
when the pending activity is done, the original handler picks up where
it left off. But maybe that's not happening, or maybe the background
activity is exiting to top.
Anyway, I'd look for background activity. An error in another script
that runs during the wait may be causing all scripts to abort.
I can't think why you'd need to add the wait in the first place though.
If you remove all waits from your test stack, does it still work there?

Thanks for responding. I can’t reproduce the problem with my test stack,
which works fine. My actual application is more complicated, and has a
fairly large map image. So, I’m wondering if that might be the cause and
I’ll have to make some tests. RC3 worked initially, but began failing
intermittently after a few seconds using the app. Incidentally, unless I
put a “wait 0.1 seconds with messages” before the snapshot command,
neither 6.6 or 6.6.2RC3 works. I tried the try/catch (no errors thrown(
and putting the result, which always returns a rect of the capture
region, it seems.
The code I use for my application is:
on copyMapToSnap
put the name of me into thisImage
set the visible of thisImage to FALSE
wait for 0.1 seconds with messages
--wait for 1 seconds with messages
put the rect of this stack into stackRect
put rectLeft(stackRect)&","&rectTop(stackRect) into theOffset
--this is the point at the topleft of the stack window
put the rect of graphic "MapBox" into theRect --This is relative to
the stack
put offsetRect(theRect,theOffset) into snapRect--offset the capture
rect to absolute screen coordinates
put adjustSizeOfRect(snapRect,1,1,-1,-1) into snapRect --remove
border of grahics box
--wait for 0.1 seconds with messages
--wait for 1 seconds --with messages
--try
export snapshot from rect snapRect to image "mapSnap"
--catch theError
--answer theError
-- end try
put the result
--wait for 0.1 seconds with messages
--wait for 1.1 seconds
put adjustSizeOfRect(theRect,1,1,-1,-1) into snapRect --theRect is
relative to the stack
set the rect of image "mapSnap" to snapRect --now set the captured
rect to the mapbox rect
wait for 0 seconds with messages
set the visible of thisImage to TRUE
end copyMapToSnap
In the absence of ideas from this list, I’m going to try adding some
complexity to the test stack and see if I can find what causes the failure.
Best,
Bill
