Thanks, Joe... I didn't even know it was possible to lock the orientation... fixed it.
Love the mapper, by the way... Fantastic job on the functionality... the only issue (minor) i've had so far is accidentally clicking the tutorial while I was exploring the options.. in order to make the text disappear, I had to go through most of the steps all over again.. closing the program and reopening wouldn't solve the problem, neither would deleting the aether and starting over, or clicking the tutorial button again in order to 'close' the tutorial. If it is not a major issue with the coding, you might want to consider adding the ability to 'exit' the tutorial (unless I totally missed how to get out of it).
