I am trying to disable the scroll zoom functionality in OpenLayers.
I have tried different things but nothing works.
First I tried this:

```
map.addControl(new OpenLayers.Control.Navigation({'disableZoomWheel':true}));

```

But nothing happened.
Then I found [this here](http://www.stoimen.com/blog/2009/06/20/openlayers-disable-mouse-wheel-on-zoom/) and I tried it but didn't work either. Actually in this case the page doesn't even load anymore.

Any ideas what to do?
