Hi, I need some help on this one...

I'm trying to copy and paste a wireframe built in an OmniGraffle file that uses master canvases into another document.

The problem is when I try and select the content on my canvas, none of the master canvas content can be selected... Thus not allowing me to copy and paste all of the contents on the canvas into another document. And, of course, if I remove master dependency, I lose my master canvas content.

Is there a way to unlock master canvas content on regular canvases?

I'm on a Mac G5 OS 10.4.8, Omnigraffle Pro 4.1.2.

Many thanks.
