Yes, the cursors do save on a stack. Another very important thing to
remember is that JAWS does not save the position of the PC Cursor when it is
saved. There are valid scripting reasons why this is the case.
To save and restore the PC cursor, I do the following:
InvisibleCursor ()
SaveCursor () ; This saves the original position of the invisible cursor
Move InvisibleToPC ()
SaveCursor () ; This uses the invisible cursor to save the position of
the PC cursor.
Code that changes positions here
RestoreCursor () ; This moves the invisible cursor to the original
position of the PC Cursor.
RoutePCToInvisible () ; Places PC cursor back at its original position.
RestoreCursor () ; Places Invisible cursor back to its original position.
PCCursor () ; Activates PC cursor.
This places the PC cursor and the invisible cursor back to where they were
and activates the PC cursor. The other thing is to make sure that the PC
cursor is active before going to all this trouble.
Some scripters do not bother to save and restore the invisible cursor.

My standard idiom is saveCursor() invisibleCursor() saveCursor(): The
first saveCursor keeps track of which cursor was active to begin with,
and the second saves the position of the invisible cursor before I
move it.

In the examples I have seen for using the SaveCursor and RestoreCursor
functions, they use the following order:
InvisibleCursor ()
SaveCursor ()
perform statements that move the focus...
RestoreCursor ()
If the save and restore functions work like a stack, wouldn't the SaveCursor
function need to be called first, and then change cursors? I am a little
confused here. I am finding my application being continually with the
InvisibleCursor active, and I am not sure why!
