After upgrading my Mac to Mojave, some GUI elements sometimes do not work anymore.
In this case above, when using the Quick Search Bar, any click on FILTER, GO TO CURRENT SEGMENT or the number 54 does not work.
Same for TM results when clicking on the number (the keyboard shortcut still works).
Notabene: This only happens sometimes.
I am using the latest CT version with Java 10 and knowing the issues Hans mentioned here. I would switch to Java 11 JDK if I knew this does not make any further hassle. Or maybe there is any default setting that breaks the GUI here.
