Parts not displaying in section view

Morning,

I'm working on a section view of a control console, and when I do a cut away view to show all the goodies inside, some of the parts just don't show up (drawing.jpg, attached).  If I slowly run my mouse over the area I can see the edges highlight orange, and I can able to put the balloon on the first of the blue modules shown in the model.jpg picture, but I can't seem to make the parts show up to save my life.  Is this just me running into a limit on my graphics card, or is there something up?  Thanks in advance; hope everyone had a great Thanksgiving day weekend.
