Perhaps if you posted some of the mouse cursor setting code...

Sure.  Here you are:

    Cursor c = this.getCursor();
    this.setCursor(dataUtils.getSqlCursor());
    try {
      ... Database work occurs here ...
    } finally {
      this.setCursor(c);
    }


dataUtils returns a Cursor object, which works fine on my development system 
but not on the user's system.

But just in case, instead of using that, I'm going to try this to see what 
happens:

    this.setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));

Ok, using a regular wait cursor solves the second problem (where the cursor 
is totally lost when
the mouse moves outside the app's main window), but I wonder if it'll solve 
the first, where
the custom cursor is only displayed while the mouse button is held down.

I'm guessing this has something to do with the custom cursor not being 
available to whatever deals
with the mouse leaving and re-entering the app window.

I think you need to learn a lot more about how the cursor works and 
responds to mouse events/listeners.

Until you learn that, using a GlassPane will probably help:
