when a hole is finished and there is the need to adjust the registered score (I also have the CT10) the screen sometimes just turns off and on making it very difficult to change the score. It is extremely annoying - I do believe it must be something wrong with my watch (have of course the newest software update). There is somewhat of a correlation with regards to warm weather and/or sunlight as this never happens when its below 20 degrees Celsius. Any advice?
