Viewing both Use Case flow and realization collab?

[Wowbagger]

I feel as though I am missing something silly here:

Is there any way I can view and edit, at the same time, both the flows of a use case, and the communications sequence diagram of the collaboration that is realizing that use case?

I can open the properties of the use case up, but that dialog is modal and locks me out of adding the messages into the communications flow diagram.

I can work around this by copy and pasting the text from the use case flow into an external text editor, but that seems silly to me.

Maybe in you open two instances of EA?
But that would only work if you have two monitors so each instance is displayed on its own monitor.

PS. Normally EA should be happy to open two (or more) instances, but sometimes it won't giving you a "failed to open empty document" error. In that case rebooting the pc should help.
