Today I found that my displayed waypoints (using BeeLine on my Axim X5 pocket PC) had deteriorated to a a crazy moving pattern of dashed lines on the map tab although they listed just fine on waypoint management. I tried reloading the waypoints to the PPC to no avail. Things got much better, with 360° of waypoints surrounding home, after I removed and re-installed BeeLine to the PPC. The GSAK waypoint file download (sans attributes) is good. It appears my BeeLine install was defective and all seems to be OK now.
Thanks for the offers of help but I doubt we would have found an absolute cause.
Will try to get out for my first cache search tomorrow morning and discover what the excitement is all about.
