Lately I have not been seeing any hidden lines when I select hidden lines display on models.  I am pretty sure in the past when selecting the "hidden Lines Visible" I would see the hidden lines show up, but now I don't get them anymore.  The Hidden lines visible and hidden lines removed views look exactly the same.  I took screen shots of a model with all 3 settings....

Hidden lines removed

Now hidden lines removed

now wireframe

If I put it on a drawing it has no problem showing the hidden lines

Is anyone else having this issue?
