How do I close the 'popouts'?

Hi Folks.

I'm a newbie using one of the pre-made rockets in Sandbox mode.  When I right click a component like the parachute I get a handy popout box with extra information - parachute opening height, rocket thrust setting etc. - but how do I un-check the box when I'm finished.  It gets in the way.  Thx.

First, make sure the pin in the upper right corner is not activated, then right click somewhere away from any part.

Thx LN400.  I knew it was going to be embarassingly obvious, just not that embarrasingly obvious!
