Screenkey Menu (INfo, Options) crash the Application

I can start screenkey, and it appear in the Taskbar of my KDE.
If i type some Text, i see chars and digits on the screen.

But if i click on the Taskbar to the Icon "info" or "Options", screenkey do nothing at all - anymore.
The Process Screenkey is still in ps shown as running process, but no Output on the Screen, no Context-Menü anymore shown at the tray.

Only thing i can do is to kill the Process.

Try to run skreenkey with serveral parameters to got some debug-messages. No message at all, for click on the Menu
