Sorry, I've been teaching all day, and this is the first chance I've had to respond.
I can play around with those settings when I get home (I don't have the laptop with me at the moment.)
I can be in front of my laptop at 4:00 PST today, or Wed between 3-5:00 PST.
The best way to reach me is email or text:
One more thought for you. Check your "start in" folder for Creo. By default it starts in the Users/Public/Public Documents folder for anything out of the ordinary. In the case of colors and appearances, look for a color or texture definition file. If possible, put all the files in this folder into a subfolder so Creo cannot see them. You could also edit the properties of the Creo Parametric shortcut and have it start in a new, empty folder.
One more item. Not sure how I missed this one last night. Run a Windows Update to see if the is a newer graphics driver for your computer. If not, try the manufacturer's site for an update.
