If I add a geometric constraint to a block, the constraint is added, grey squares are added to drawing where the constraints were added... but instead of the symbol for the constraint on the grey square icon background, there is just a grey square. Hovering over it... changes color and expands below to show the [hide] 'X', and tip displays correct constraint name. So it all seems to be working, just not displaying correctly.
FYI - icons on toolbar all display fine... it's only in the drawing that they do not display correctly.
Am I missing a setting? Any ideas?
