One of the cool things about sql nav is intellisence - specifically using uppercase for select words. (select,insert,from type of stuff)
But something happens while developing code - that the intellisense stops using capital letters for sql. uppercase SELECT becomes lowercase select. But select will still be blue just not capitalized.
This drives some of my developers crazy. (which I like to do just for general principal) However they have asked that I point this out to quest and hope you can fix this. This has happened in the new editor on 7.0.
Good luck quest. We have had a hard time finding the cause over here.
