Dear scooterchris. please explain to us how you get the mentioned altitude. And if you may, show us the configurations and versions you are using. Plot Thickens!
(I haven't t had so much fun since my Lisa became Mac!)
Dear Chris
You just cost me $2000 ;-)
I was holding my decision to get the P3 for repressing things like this of the maximum altitude.
I live in Cost Rica and we have various mountains which we like to hike and bike!
Give us more info about your experiment please...
