Strange thing happened the other day. I was on a long walk, and at some point while messing around with my phone, I accidentally clicked the x (the close program button) on the eCoach window. Luckily a prompt came up and asked if I wanted to stop the exercise or not. I clicked no, but the program closed down anyway! After that, eCoach wouldn't start up again until I rebooted the phone. And after rebooting, the walk I recorded was nowhere to be found.
