While in the hangar I do the following:
Select 'skin' menu such that pulldown opens.
Select 'default' in the field, rather than the 'default' listed in the pulldown display.
Red 'cursor' appears in skin field. No key commands or mouse cursor move-clicks work until I select on the 'default' (or other if available) selection from the pulldown skins menu.
If I hit 'Esc' while the red cursor line is still visible, the clipboard disappears and I can't recall it because the keyboard is deactivated. I am therefore forced to do a reboot since I can't get out of the hangar (all keys deactivated).
