I'm guessing that no one knows a way to do this, hence the lack of response. Not that people are unwilling to be helpful.

My suggestion would be to magnify your view when making these types of adjustments.

Btw, if you need to get a response from the OmniGroup, use the Send Feedback... menu item from the Help menu of OmniGraffle. While they browse the forums, they can't guarantee that they will be able to respond to everything on here.
