Some functions are active when you select a topic and some are active when you select a relationship or boundary.
Line effects are active when you select the relationship or boundary, but cannot be selected for topics.
Thanks a lot for the answer. The thing is that I cklick on releationship (line) and even that is not to select. It is a new map, and i create new top down releationship boxes (like a org chart). I can select the box but not the lines connecting them. That is my problem. So there is also no chance for line effects ...
And I do not know why.
On windows systems I remember, it was the case, some functions were inactive if you have no license. but I have one registered.
