All the GPS apps we use have been strangely flakey. They will all suddenly stop updating despite there being evidence the phone knows its location. Sailties was killed at the same time as Adv-Traveler so I'm beginning to think once I finally resolve the straight line bug that it'll be close to "industry standard" ... I still think for the time being that we'll keep it at a boutique level while I focus on the read-only ARM app ...
