Jigsaw and The Southern Cross

Jigsaw in Turkey and S to Egypt half finished - just to test .kml/.kmz and GE itself, because I have had difficulties with a .ptf file from TSC.  GE freezes on acer and crashes on desktop.  I think I need help from Alan M because the slowness seems to start there.....   chopping the files doesn't seem to help at all.... However the short last Maryland track works normally....More to be done!!!  Ah.....it seems that the high resolution of the track produced more track points than GPSU and GE were happy with. I removed all points E of Gib and then divided the rest into monthly packets. All now seems well.
