Cursor not showing up in standalone

[Stgoldberg at aol.com]

I hope this is a simple matter and I'm just overlooking the obvious: I'd like 
the cursor to change to a magnifying glass when the mouse is down, so I've 
written:

on mouseDown
set cursor to 378
set lockcursor true
end mouseDown

This works fine before the standalone.   But after the standalone, the cursor 
does not show up either on the Mac or Windows version (I'm developing on a 
Mac OS X).   I've also checked off "Select inclusions for the standalone 
application" and "Cursors"   in the General Standalone Application Settings.   Am I 
missing something?   Thanks very much.
