I use the global weather update every 15 min. and on some flights I just happened to check the weater menu because the weather didn't seem to update. I noticed that it switched to user definded weather. I clicked on the update weather every 15 min. and weather changed to the correct weather for that area. After flying awhileI checked it again and it changed back to user definded. Changed it again and flew some more and checked again and the weather in the menu stayed at global weather update every 15 min. So I kept flying and a little while later I checked again and it went back to user definded weather.I can't figure out why the sim is not staying on global weather every 15 min.Anyone else have this problem?Thanks

What other programs are running besides FS?

Hi Jim, I think I figured it out.I had a box checked in fsuipc that allows changes in fs own weather.With this checked it will any weather themes selected will keep reverting to user defined weather.I'll check on next flight.Thanks
