Make sure that you don't have 2 new OpenLayers.Control.Navigation defined 
in your code

[OpenLayers-Users] Problem: each mouse wheel step results in two zoom 
levels








Hi
 
I noticed a problem in my application. Each time I rotate one step of 
mouse wheel, two zoom levels are changed. That is not right. It should be 
just one zoom level.
 
Any idea?
 
I am using 2.11. And it happens to my application on both google base maps 
and wms base map. I changed numZoomLevels from default of 16 to 22, and 
the same things happen.
 
Thanks.
 
JK
