Midway through my ride yesterday, the "moving time" had an extra 24 hours added.  The "total time" does not have the extra 24 hours, so it showed up as a total time of 3 hours and moving time of 27 hours, which of course affects the moving speed.

This is the second time it has happened; the first time was a couple weeks ago, after no such problem since I started using it ten months ago.

Any ideas or cures?

Thanks,
John S.
