I did now some reboot/resume tests: - suspend with Dock connected/resume -> issue appears - reboot with Dock connected -> issue appears - shutdown with Dock and start with Dock -> issue appears -> in call cases log out/log in solved the issue - shutdown with Dock and start without Dock -> OK It seems related either to this laptop and dock or maybe to multiple (1 + 2ext) monitor setup? It in call cases the APP responded to key short cuts still.
