Comment 1 for bug 56219

Hmm - curious, using the new diagram button, creates a new window, which will allow placement of components and wires. However, switching back to the original window still manifests the issue.

I have tried many things to reproduce it, and just cannot seem to do so at will, but then when I am just working in the diagram, pop and there it is again.

What more, after many attempts to reproduce the issue with two documents open, one with the issue, one not showing it, I actually managed to completely crash the application.
