a.k.a. Richmond's longest-lasting headache
imagine this sort of script:
on mouseUp
set the useUnicode to true
set the unicodeText of the selectedText to numToChar(2340)
select after the selectedText
end mouseUp
all looks straightforward (nicht?), but 'tis not to be . . . :(

My user types a search target and presses Enter or clicks the Find button,
and his target is found. At that point I want the focus to return to the
input field so the user can type another target. I find this surprisingly
difficult to achieve.

With the focus gone, my user will probably try to press Tab to return the

buttons receives that Tab keypress.

So if a script wants to find out the system font, and the above is added

I ultimately did do some kludging. It was grim. I use VBscript to open up a
notepad document, then use sendkeys within the vbscript to paste, select
all, copy, and close the notepad document. This works, but it has to be
visible in order to work, so it is not very elegant.

After hearing everything that has been said in this thread (mostly by
Jacque, but also by others), here is the solution that works.
To recap briefly, the problem is what Jacque calls the engine's
long-standing behavior

Hello,
I've never tried scripting for a quicktime player. Tricky. A few tips would be
helpful.
In the stack I'm working on, there's only one QT player per card. The filename
of the player is already established at openCard, the sound files stored on a
local volume. They are in m4a format if
Hi Tim:
Try setting the startTime of the player to what you need (you may need to do
a conversion from player units to seconds). Alternatively, you can set
the playLoudness property of the player to 0 (although I seem to remember
someone running into an issue where setting playLoudness to 0

This works because you are sending in time, after everything that would have

Hi all,
To me, once globals are defined and put with a value, their value should be
available from any stack within the application.
So far, so good.
But the problem arises where, within other stacks script, if you don't
define the required global again, the desired value is not there.
The
Do you mean that if you declare and load a global, say yourGlobal, that you
should be able, in any other script, to just write:
answer yourGlobal
and retrieve that data?
I find that variables, script local variable and globals are treated just
right. I could be old-fashioned, though.
Mark,
When I define a global in the main stack, it is available to all its
substacks. Are you sure this is not the case in your application?
You may have already seen this in User Guide:
2.2.4 Main Stacks and Substacks
The first stack created in a stack file is called the mainstack. Any other
if you don't define the required global again, the desired value is not
there.
You have to declare the global in the script where you want to use its
value, but you don't have to define the value again.
from the Main Stack script:
global gMyName

The difference may be that in other languages you are generally working
