Stopwatch Bug 60592:07:48

I use the stopwatch as a lap timer when I exercise, but it freaks out when a call comes in when it's running. Before I did this I tested again to be sure. I opened clock, went to stopwatch, and started it. Pressed the lap button at 3 seconds, and then turned put the phone to sleep. I then placed a call to my cell phone, answered it, and hung up. When I went back to the stopwatch it had stopped counting that lap. When I hit the lap button again it said that lap was 60592:07:48 when in reality it wasn't more than 20 seconds. Seems like this happens when I get text messages too. After I hit the lap button I hit the sleep button to save battery life, and then wake it up again before the laps over. I do that all the time with no problems, but a phone call just screws it up. Sounds like a bug to me.
