I have come across an issue with Visual Micro (VM) using Visual Studio (VS) 15.5.7.

When I compile and upload my code onto an Genuine Arduino Nano 328 and I select VM "Automatic Debugging (release/debug)" my code compiles and uploads correctly but it does not do what is expected.  I have set-up a PWM pin output (Pin 10) to pulse at a 10% duty cycle.  The only code is as follows:

void setup ()
{

analogWrite(10,10);
}

void loop()
{
//nothing here...
}


As the code starts to run, I see PWM pulses appear on my oscilloscope for just a flash (1/2 second maybe?). Then it output goes flat. 

If I compile and upload without VM "Automatic Debugging (release/debug)" enabled the PWM output pulses hold without interruption - as expected.

The above happens with our without VS debug mode enabled.

I'm at a standstill on why this is happening. Seems like a bug but I'm new to VisualMicro. Any input would be appreciated.
