S60 / CT10 failing to complete hole

On a couple of occasions the S60 has failed to complete a hole after the final put, it just stays showing the distance and ‘done’ does not appear.  it loads the next hole, but the score is totally missing from the final summary, although each stroke played is shown on the graphic display, It means that ine has to edit the missing score and enter manually if you can remember the score for the missing hole. Very annoying. Anyone have a solution.
