I have an issue if I try to upload to a Mega2560 I can do it once but if I stay in the app and try a second time it does nothing. It just waits and I have crash out of my app. If I restart my app I can then upload again. I know its not my app as it doesn't do the same with NanoR3 or UnoR3, they work. I know its not my board as I dont have the same issue with the Arduino IDE.
