Hi,
Check with Firebug which kind of requests your application is really sending to Geoserver. It looks like it can use WFS and GetFeature but until now I have believed it is WMS and GetFeatureInfo. Actually you would probably get better answers from OpenLayers list.

map.addControl(control);
control.activate();
Note the clickTolerance line

Hi
Thanks for the replies
Ive tried
vendorParams: { buffer:100 },
tolerance: 100,
in the openlayers wmsgetfeatureinfo request but no change, the points are still very difficult to click even with these extreme settings
From the open layers docs tolerance doesn’t seem to be a supported parameter anymore though

Mark,
You might take a look at the clickTolerance setting as described at the link below:
http://dev.openlayers.org/releases/OpenLayers-2.13.1/doc/apidocs/files/OpenLayers/Control/GetFeature-js.html#OpenLayers.Control.GetFeature.clickTolerance
Hope this helps.

Subject: [Geoserver-users] openlayers WMSGetFeatureInfo and geoserver too sensitive
I am using openlayers 2 and issuing a WMSGetFeatureInfo request to geoserver
It works fine but It is far to sensitive to where you click – if you don’t get right in the centre of a point or icon it finds nothing, it can take 2 or 3 attempts to get a response even if clicking carefully and zoomed in
Is there any way to make that click “less sensitive” so it will pick up the closest point to the mouse click ?
I know this isn’t strictly a geoserver issue but I’ve found nothing useful on the openlayers forums
