Bamboo, Good job on describing when the bug occurs The only thing you need to add is that you were using StandardForm or TraditionalForm for input (I believe), as I was unable to duplicate the problem when the input was in InputForm. I think you ought to report this to Wolfram. As far as a workaround goes, I agree that the change in color scheme is a pretty good clue that a problem has arisen. Why don't you just fiddle around with the input by adding and deleting spaces to get the background color to be uniform again? It seems to me that when the background color is uniform, the bug doesn't occur when you save and reopen.
