Hello,

Using my SmartComponent RsDrawGraphics, I cannot connect to controller after it is loaded. (Real or Virtual)
With RS 2019 it's worked well, but with RS 2020.1.2 I can't without message.
With RS 2020.2 this message appears:
RobotStudio .NET exception: A connection with systemId {204105E0-E849-48AD-BFB9-7A2274807590} has already been added.
============================================

The connection to controller in RsDrawGraphics occurs here.

In my dev machine, I have an older RS version due to new license system, so I can't debug it.

Can someone tell me what I've done wrong?

PS: If I connect the real robot then load station, all works well.
