	Hello, I have the following strange issue. I have implemented a code using two classes calling each other. A very abstract version of it can be found in the attachements. If I run the code on the Arduino and open the Serial Monitor I see these lines: Opening port Port open but no other issue is mentioned. Interesting is now: 1) If i delete the line 35: Serial.println("CurrentArrayPosition:aaaaaaaaaaaaaaaaaaaaaaaaaaa"); the skript is running fine. 2) Within the Arduino IDE the original Code is also running fine Tried with: Visual Micro 2020.321.3 Visual Studio 16.5.4. Arduino IDE 1.8.10

	For accurate test please ensure:- 1) The tool bar says Release and not Debug 2) The DTR checkbox is enabled in the serial monitor 3) The speed on the serial monitor bottom bar is set to 9600 Thanks

	Great. The issue happens because the setup runs very quickly very early in startup, therefore some things can affect if the serial window has started before the message arrives on the pc from the mcu. Things to keep in mind The DTR is important because it causes the mcu to reboot when serial starts. Arduino IDE always has DTR on, in Visual Micro is defaults to on but is optional. If debug starts when the DTR if off then the mcu does not reboot and the setup() does not run. When debug is running more is happening and it's possible for the very start of the mcu code to be missed. Adding a delay of 2 second to the start of the setup() can resolve that issue if debug is needed in setup(). Adding a breakpoint or using the auto created tutorial breakpoint will cause the mcu to stop/pause (unless the breakpoint has "Continue Execution" enabled). When the mcu is paused there should be messages showing in the VS status bar and trace.
