At times I get an object stuck in transparent outline mode, it displays that way no matter what display mode is selected. The only way I've found to cure it is to open and save it in tS 3.2. Dunno if some version between that and 6.6 would also work.
I'd love a plugin or some way to correct it within 6.6.
Here's a small example of an object that's stuck in that display mode. It's a piece of my Cosmo Gun. It flipped like this just as I was finishing up and I wasn't even working on this part.
