[OpenLayers-Users] double clicks on button control

[Dave Rafkind]

I would like to add an extra button control to the map, in addition to 
the standard nav buttons. This additional button will do something when 
clicked. This works fine as normal.
However when the users double-click the button that i have added, the 
underlying map picks it up and tries to do the "zoom-in-and-center" 
action at the point on the map
that the button control happens to be over. I believe this is because my 
Button control is not consuming "Double-Click" actions and is instead 
passing them to the underlying div(s). So I'd like to see if consuming 
and destroying the double-click function from my Button will solve this. 
If there is a different/better way, I'm open to that as well.
