Hi,

I have run into a quite puzzling issue: I have created a symbol containing a pushbutton. Switch is a released property and I use it to trigger an event in my driver extension by linking a bool variable to it, which is true as long as the button is pressed. My problem is that the button is invisible when the Service Engine starts, but I can click it. After it is clicked, it is permanently visible, so it is not a wrong setting in the visibility/flashing category. What makes this even more interesting is the fact that the issue is present only if the button is linked to a variable that uses the "GENERICNET - Generic .NET driver" driver and Driver Object Type is set to PLC marker. If I understand correctly, this is the best way to trigger custom events in the driver extension. If I switch to the communication details Driver Object Type, or a completely different driver, the button is visible on startup. The button's switch, pushbutton, and Pushbutton on properties don't affect the bug either.

I would be grateful if you could help me with this.
