[OpenLayers-Users] Selectfeature not firing

[Alexandre Dube]

Chris,

What you're describing is a normal behavior when the Navigation and 
SelectFeature control are both activated, yes. To resolve this, you could :

* have a toolbar with your controls as buttons and only one is active at 
a time
* have your SelectFeature control clicks work only while pressing a 
specific key (ctrl for example). This could be done by defining a 
'keymask' to the Handler.Feature object of your SF control.
* make the "select" on "hover" instead of "click", see an example [1]

Hope this helps,

Alexandre
