Hi,
Yes Andreas, using console as you said, I get two navigation controls, one
added to map as a control, and a seccond added as a geoext action to get a pan
button in the toolbar.
I've dropped the seccond because is not necesary.
Anyway, I've configured control with: mouseWheelOptions: {interval: 20,
cumulative: false}
Best regards,

Tema: Re: [OpenLayers-Users] mousewheel jumps two zoom levels
My guess is that you have two Navigation controls. One that is added to the map
by default unless you configure it with your custom array of controls, and the
navControl you added.
You can check in the javascript console by trying
map.getControlsByClass("OpenLayers.Control.Navigation");
and see if it returns an array of length 1 or 2.
The obvious fix is to configure the map with your own default set of controls.
Andreas.
