Distance prompt dont work on Fullscreen mode?

Today i found some strange situation. When i press fullscreen prompt, distance command line wont work. Is this normal on Rhino 5 SR12 64bit on Windows 7?

Hi Antonio - any command that reports results at the command line like Distance, will not show anything if the command line is missing - is that what is happening? You can use -Fullscreen to set the options for what to show and what to hide in FullScreen.

if i correctly understand your reply, yes. The command wont work only in fullscreen mode, when it cover the line command. But if i move that viewport to the external monitor it work with no problems.
thanks
