Updating again...sorry for jumping to a conclusion without fully testing it.  Since making the previous post, I've been dumbfounded by the problem cropping up again.  Apparently this fix only works for "some" character models.  Victoria 4 and Michael 4 seem to still be suffering from the OpenGL issue.  So my "fix" may not help much if you're using these characters.  Best suggestion is try it and see and await SmithMicro to finally admit a problem and fix it for sure.

If anyone notice the "save Pz3 and reopen" works for certain characters and not others, feel free to post IDs here.  I'm rather curious as to why this works for some and not others.  Figuring out which ones are working and which ones aren't might point us toward a solution.
