Get this message every time after about 10 mins. of usage of Active Sky. Any help?Also, in a previous post I was referred to a manual. Where can I find that? There wasn't any in my zip file (version 1.1 downloaded from FLightsim.com)Chris

The manual only comes with wxRE the full payware version. Sounds like you have the freeware version? If so look in your ActiveSky folder & look at "Docs_ReadMe". Hope this helps!
