How do I rotate of exactly 90 degrees with the tween behavior?

When I use the tween behavior to rotate an object of 90° at every click, if I repeatedly click too fast, after a while the object angle is no longer initial angle+90 but something else. How do I make it rotate exactly of 90 degrees everytime even when I click the mouse fast?

Add a condition to prevent the start of a new tween while a tween is already running.

What would be the action?

-> Sprite: Tween "rotate90" property Angle to Self.Angle+90 in 1 seconds (Default, destroy: No, loop: No, ping pong: No)

What was the result? What didn't work?

It still doesn't stop when the tween is playing so if I click repeatedly the object rotates more than 90 degrees.
