I am trying to actually HIDE the "hidden" lines.  I have selected the "Hidden Lines Removed" button, under the "Display Style" section.  Yet, the hidden lines are still showing.

I began RMC'ing each line and started hiding them that way.  However, I shouldn't have to go through all of this, considering that I am trying to select to actually "hide" all hidden lines.  There are too many hidden lines to do it manually.

Anyone know what can cause this??
