Hi Douglas, I do run skymaxxpro + 10.30b3 having no compatibility problems at all. But, i do have clear skies (as many other people) quite often. Xplane 10.30 has a new metar weather report parsing algorithm which is still being tweaked so far leading into clear skies sometimes So, do you have clear skies due to skymapxx+10.30b3 issue? or do you have clear skies due to metar parsing issue leading into clear skies? Please: 1. Open localmap, clic over your airport code, a window will popup top-right having your airport frequencies and weather conditions. Do a screen capture and attach here. 2. Also, please attach the metar.rwx file at your xplane root directory I will check it out for you to understand what may be wrong.
