KLayout uses the mouse wheel to zoom or pan and the behaviour can be adjusted in the Setup "Navigation/Zoom and Pan" but it cannot be switched off. Apples Magic Mouse uses a touch sensitive casing that is used as 2 dim mouse wheel and is very sensitive. It is great for scrolling pages but in KLayout it is much to nervous and permanently induces zoom/pan operations.
Is there any way to switch the mouse wheel off?
Note that setting the "Pan distance" to a very small value doesn't not solve anything. Movements are still triggered, albeit very small steps. But then the same is also applied to Pan/Zoom triggered with the keyboard which is not useful.
