hey,
I'm evaluating StarUML for use in our organization. One thing that seems to be a little of is that I'm not able to open multiple files at once:

I would think that I can switch between diagrams in the "working diagrams" window, but I can only have one inside that window. Also if I double click (open) another file in Finder, the view in StarUML is not updated and displays the old diagram. So I have to close StarUML and then reopen with another file.
What am I doing wrong?
I'm using StarUML 2.7.0 for OS X 10.11.5
Cheers,
Daniel
