I have two displays – macbook pro 15 and Cinema Display 27. When using both ow them there is a trouble – context menu appears on one when in was calle on another
here is how it looks http://daniyar.com/temp/screen-GMrVZtBl5m.jpg
iMac, OS X Mountain Lion
also changing name for example http://daniyar.com/temp/screen2-t90jX8OXoJ.jpg
Does this happen only if you attach the external monitor when the system is already booted, or does it also happen if you reboot the system with the monitor attached so it loads in a dual-monitor environment?
Already attached. Guess it's a bug of Mountain Lion
If you detach it the monitor so the screen goes to single-screen mode on your laptop, and then re-attach the monitor, does the problem persist? This is definitely not a universal issue in Mountain Lion.
Try creating a new user account and then log into that account to see if the problem persists in that account. This will indicate whether or not the problem is with an account-based setting or is more global.
Context menu problem, bug
