Hi,

We're setting up a new Hmi (Mtp 1500) in Wincc Unified V19. We disabled some buttons with the property allow operator control. The buttons are greyed out and when pressing on them they don't do anything.

But when pressing the button using two fingers: click with the first finger, hold the button and then press with the second finger the button get's activated. The event was programmed under "release".

Did someone else notice the same behaviour ? 

We did "fix" it now by blocking the action of the event in the plc.
