I have Omnigraffle 4, and I'm trying to create an action to jump to another canvas. I'm able to select "Jump elsewhere" in the Action Inspector, but then I'm unable to select another canvas to jump to. Is this possible at all in Omnigraffle 4? I would upgrade to OmniGraffle 4 Pro, but before I put in $100 I need to make sure this actually works. I can't upgrade to OmniGraffle 5, because I'm running Tiger.
