After setting up my NX 11.0 environment a glitch happened and now I have double the vertical spacing and a multiple selection icon stuck in the upper left corner of the screen. With an accidental click of the mouse I saw this entire reformat take place but have no Idea how to get it back to the original. When I go into customize the icon disappears and when I exit customize it reappears. Has anyone else experienced this before. Thank you.
There was a similar question posted recently. The icon you see represents something for the "touch" interface. Go to roles -> presentation and choose the "default" option.
That was it! It turns out I inadvertently activated touch mode. Thank you very much for your help. I'm back in business.
