Forget that Captains, I've sorted it.

Hi Captains Again, when trying to fly an IYP flight today from Charlotte to Fort Lauderdale , my battery died just as I was about to perform the Before start-up checklist. I checked that my simulator had focus, it did. This is most perplexing, as last evening, I powered up a 747 in terms of switching on the battery master switch, and left it alone for an hour. All was well upon my return, the battery was indeed magic. I post below my FSUIPC4.ini file in case anyone can spot something: [General] MagicBattery=0 UpdatedByVersion=4800 History=EIV4V4G1SOMRTHBS1VO9A AxesWrongRange=No TCASid=Flight TCASrange=40 AxisCalibration=No DirectAxesToCalibs=No ShowMultilineWindow=Yes SuppressSingleline=No SuppressMultilineFS=No AxisIntercepts=No DontResetAxes=No InitDelay=0 GetNearestAirports=Yes WeatherReadFactor=2 WeatherRewriteSeconds=1 CustomWeatherModify=No SimConnectStallTime=1 LuaRerunDelay=66 FSVersionUsed="Microsoft Flight Simulator X",10.0.61472.0 SimConnectUsed=10.0.61259.0 Console=No [JoyNames] AutoAssignLetters=No [WideServer] WideFSenabled=Yes [Sounds] Path=C:\Program Files (x86)\Microsoft Games\Microsoft Flight Simulator X\Sound\ Device1=Primary Sound Driver Device2=Speakers (Conexant 20672 SmartAudio HD)
