Hello Dmitry
About error message 2 (error2.jpg), I noticed a recurring thing : when this message appears when I press the RUN button, the project does not start.
At that time, I did not save anything from my project. I just want to test it.
But if after viewing the message, I save before running the RUN button, it works fine.
I use version 3.5b (26/05/2017). With previous versions no problems.
Maybe a bug?
Thanks in advance
JB
