I have a blinking LED using timer interrupt. This is what I use to check 
if the board is working or not.
When I program the board with debugWIRE and run the code, the LED stops 
blinking in on or off state just after I press the reset button.
After more tests programming and running the code, I left the debug 
session after pressing "disable debugWIRE" in AVR Studio. It was a 
surprise for me the board restarted running my code after I pressed 
reset button.
My conclusion is the board stays in debugWIRE mode unless I press the 
disable debugWIRE in AVR Studio. If I do not press the button and exit 
the software, debugWIRE is not disabled and something wrong happens when 
I press reset button.
Solution: always press "disable debugWIRE".
