Enterprise Architect sequence diagram: cant select operation or properties

[[email protected]]

I am using EA Program Version: 15.1.1529 (Build 1529)

I have created a simple sequence diagram with two classes as vertical line on the diagram.
I create a message between the two classes without any issues.
I then right click on the message and want to select a public operation defined by the target class.

I am unable to right-click on message and find any UI to select any operation from the target class for the message.
When I try to right-click on message and select properties nothing shows.

What could be wrong?

There are no classes to be used in an SD, only instances! EA lets you use classes, knowing that it's wrong and clobbering what you did once you ex-/import via XMI. Somewhere in the docs you find a warning. Unbelievable that this is still not fixed after so many years.

I am unable to right-click on message and find any UI to select any operation from the target class for the message.
When I try to right-click on message and select properties nothing shows.

Properties show in  the 'Properties' docked window. In that window the top field should be a drop-down with the available operations from the target or you can click the button to select one using a dialog. (I don't have 15.1 running, this is from memory)
