I have SkyDemon 3.4.1.0 on a PC running XP and SkyDemon Mobile 3.4.0. During my last two weekly flights the SD Mobile Flight Log kept stopping and then starting again. When in SkyDemon Plan Analysis mode the route flown is broken into several segments and is also shown as discrete entities in the Mobile Flight Statistics window. The SD Mobile continued to work correctly apart from the logging function.

I use a Cessna 152 fixed wing aircraft and it has only happened the last twice I have flown. They were 2nd and 9th September 2015. I normally fly each week and have used the SkyDemon equipment for a number of years without knowingly losing the GPS signal.
