I'm also having problems with altitude, but a little different...
Before in previous versions it was okej: http://www.gps-sport.net/trainings/Krog+Ljubecna_6337
But now the altitude diagram is not okej: http://www.gps-sport.net/trainings/KrogLjubecna_9268
I use Glifiish Eten X500, static mode disabled for SirfIII GPS receiver.
As you can see on my profile, the altitude/elevation is logging fine, but the total ascent/descent always reads 0. This is a good counter to measure my performance by when cycling and mountainbiking, and would like for it to work. Are there any known issues with this function for my application (Verizon XV6800/HTC TyTn, WM6.0)?
