#4 I can't get access to Preferences

[HeRo]

ClipIt works now (2 months ago it didn't really...). But I can't seem to get access to the preferences (2 months ago I could...). I use Ubuntu 18.04 LTS (until 1 month ago I used 17.10).
Whether I right-click or left-click on the clipit-icon I just get the list of clips.
Can anyone help me?
