I was trying out the linkback feature in OG5 but can't get an object to linkback from one omnigraffle file or canvas to the original. I followed the help file (below) by drawing an object, choosing Copy > As PDF, then pasting it on another canvas and in another file. When I double clicked on either, I got the osx beachball for a few seconds and then nothing happened. I wasn't taken back to the original instance of the object like I expected. Am I doing something wrong?

Here's what the OG5 text file says:
"To embed OmniGraffle content inside a single object in OmniGraffle, choose Copy As PDF from the Edit menu, then Paste normally. The objects you copied become a single image; you can double-click the object to edit the original content."
