Press Ctrl+Q for a full rebuild and you'll get the expected behavior (both ways).
Also, as an aside, the layer print toggle setting is set to not print when you turn off a layer, but it remains non-printing when you turn the layer back on.
AutoCAD has had this feature for many years and the two settings are correctly independent.
Seems odd that SW couldn't separate these.
Anyways, my diatribe is over.
Ctl+Q!! Awesome! works great!
