objects getting stuck together
 

I've encountered an odd problem with OmniGraffle Pro 4.2.3. I've created a complex diagram with circles, lines, and polygons. Somehow some of the objects have got connected together (they are not, as far as I can tell, Grouped). So I select a line that I want to delete, but when I delete it, half a dozen other objects go with it. Interestingly, if I select one of those other objects and delete it, just that object goes and the rest remain.

So, in some way the objects are getting connected or dependent on each other, and since I don't know what this kind of connection is called, I don't know how to find it in the manual.

Thus, I have two problems: Disconnecting the objects in this diagram so I can delete them individually, and preventing the problem from happening in the future.

(As far as I know, I have magnets turned off and connections disallowed for all the objects.)

Thanks for any help,
Bruce

Sounds like the shapes have gotten accidentally converted into line labels for the line (you can do this pretty easily by dragging a shape onto a line).

I'd try dragging the shapes off of the line, then going into the Connections Inspector for the line and turning off "Allow shapes to become labels".

Hope that helps,

Mystery solved! Thanks!
