Has anyone noticed some document properties in the options tabs changing on their own or not updating when changed?

Specifically I was changing the precision of the dimensioning in the document tab under options and it would keep reverting back to "none" when i was setting it at .123!!!

I had also noticed a similar thing ocassionally happening with configurations when configuring dimensions or features etc and using the popup box to change all configurations at once. When you opened up the configuration it would have reverted back to its original state and not updated as requested.
