I have two stacks in one folder 1) Guestbook_engine.rev 2) Guestbook Records.rev in the same folder I though that a button in stack 1) on mouseUp go stack "Guestbook Records.rev" toplevel "Guestbook Records" end mouseUp should work to open the "adjacent" stack 2) but it doesn't what am I missing? I need this to be portable. Sivakatirswami
