Impossible to add input parameters in UML class operation
Hello,
I'm building a UML diagram with dia 0.97+git on Ubuntu 20.04.
I'm trying to add an input parameter to a class operation but when "Direction: in" is selected, the parameter disappears as soon as I click elsewhere. I did not experience this behavior when I used dia on Ubuntu 16.04.
Let me know if you require more information about my system configuration.
