I used to change sketch colors to help separate from other sketches. But ever since i upped to 2012 SP3.0 i can't change the sketch colors. I have right-clicked on the feature in the tree as well as the sketch entity itself but neither way will work. The "sketch/curve color" dialog comes up and I choose a color. The entities will change colors only as long as the dialog is open. But once the dialog is closed, the sketch color goes back to the default grey. Here is a reference part i created that will not change:

Thanks.
