Hi Umberto,
Ok, so I have done a clean re-install of windows 7, re-installed FSX standard with acceleration, FSUIPC4 and GSX v 2.2.0.1
I have loaded the default 737 at EDDM gate 6 and requested fuel, the fuel truck arrives and I custom load 50% in all three tanks and remove all passenger weights.
The re-fuelling procedure completes with no problems, I check the fuel/payloads weights and the fuel has reset to 100% in all three tanks and the passenger weights have returned to maximum.
From this I can only assume that GSX is doing something, would you agree on this Umberto?
Apart from FSUIPC this is a clean install of both windows and FSX.
Any help on this would be very much appreciated.
Thanks
Dave
