¿Cómo se quita la ventana de “operaciones” en la etiqueta “ERROR”? a cada instante venta y se vuelve molesto cada rato tener que darle clic en “IGNORAR” 
The errors are shown for a reason. It means something is wrong! Maybe better to just solve the issue then the window will not show.
But if you want to disable it go to Menu > Tools > Settings > General > General > Operations Window. Then untick Show window when an error occurs.
