I have three .gpx files which MapSource (and Find/Count in Notepad++) says have more than 500 trackpoints. I've loaded each into Bikehike with the intention of reducing them to less than 500 trackpoints. Unfortunately Bikehike's options dialog reports them as having less than 500 trackpoints.
All three files were cut (in MapSource) from my tracklog of the Dean 300. Each consists of several hundred trkpt elements within a single trkseg element, within a single trk element. There is nothing strange about the nth trkpt, where n is the number of trackpoints reported by Bikehike. I've tried editing one of the files to remove the metadata/bounds element (with its maxlon, maxlat, minlon, and minlat attributes) and reloading; this makes no difference.
Does anybody have any idea what may be going wrong? I've used Bikehike to do this several times in the past, but not recently.
(Sigh, I wanted to get this finished before starting work for the day).
