[OpenLayers-Users] Hard to click on points for GetFeatureInfo

[Marc Desharnais]

Hi all,

I'm using geoserver so I guess your solution won't work. Anyone has an 
idea about setting a tolerance level in geoserver?
Or anything that would make it easier to click on a point of a map with 
geoserver.


Thanks,

Marc
