Update:

I reviewed the settings on my V7 yesterday in detail. Apparently after upgrading the V7 software, some setting survived and some didn't.

I found that my Polar screen settings were completely lst. They now showed a "Default" glider type, class " unknown". It also showed stall speed at 10 Kts., the polar showed A=1.94, B=-2.9, C=1.6 glider weight --lbs, max glider weight --lbs, empty glider weight --lbs,

I have corrected these settings, but have no way of testing wether they fixed problem #3 (see first post) without doing a flight test. Stay tuned for more info.
