Selecting Edges Through Faces

I know this has been covered before somewhere, but I'mbringing it up again as it's a pet peeve and has not beenaddressed.

I have the option Display/Selection "Allow selection in wireframeand HLV modes" toggled on under my system options to be abel toallow me to select edges that are hidden inside a model; butinvariably this toggle gets unselected, and not by me. I have noidea what combination of things I'm doing causes this, but I find Ihave to go back and toggle the switch on again after wondering whyI can't seem to select an edge! Please lets make the options youset stick till YOU want to change them.SolidworksGeneral
