You might try deleting the track history or at least deselct "Show" on the "Track" menu. Also consider setting the track interval to "90" seconds.

What happens is so many track records get accumulated and processing them does take more time.

Thanks, yes the track file was almost 10 mb, mybe i have the time interval to short. so it is better to export track more often and track for a sorter time. track for 24 hour and export the trac and start over. thanks
