creative cloud application manager disappears

Hi everybody!

I have installed CC on my Macbook Pro with connected Thunderbolt Display.

Everything works fine until I disconnected the Display and made restart.

The icon of the CC application manager appears for a second in menubar and then fades away.

CC works fine but I can only make updates or installations with connected thunderbolt display,

because in this mode the app manager appears and works....

Reinstall the App Manager brought no better results. Anybody with the same problem?

Thanks and best regards,

Karsten
