How to attach a fixed connector to an object that has internal objects?

[Neutrino-Sunset]

For example. How do I attach a fixed connector to the bottom of a UML class? Because the class object has inner objects (for attributes and methods) attempting to drag a connector to the bottom of a class selects those inner objects (which don't have connectors at the bottom).

The only way to attach any fixed connectors to a class is by hovering the mouse over the class name in the upper class box, and then you can attach to one of the upper connectors, but moving the mouse anywhere else in the class selects the internal components.

Fixed connectors attached to internal class attributes is a problem for several reasons. Firstly they only have one connection point on each side, and secondly if you delete an attribute any connections are disconnected and left hanging.

This makes it impossible to attach fixed connectors to either the bottom or sides of any class.

I have just found a partial workaround, which is to collapse the class you want to attach a fixed connector to first, then you can use its bottom connection points and re-expand the class afterward. But it took me a couple of hours to work this out and even this doesn't enable you to use the connection points along the side.

Is there a better way?
