Hi,
Did you try to find the problem first? You seem to run your own Mapserver.
Then you can see from the Apache access log the requests that your client is
actually sending. MS4W installation the log file is by default at
ms4w\apache\logs\access.log
Add DEBUG 5 into LAYER definitions in your mapfile. Copy and paste some failing
GetFeatureInfo request from access log and resent it with web browser. See
what comes back, and have a look at the Mapserver errorfile which collects the
DEBUG data. It might be better to send GetFeatureInfo requests first against
polygon layer because then it is easier to hit a feature by mouse click. By
hand editing the request you will have a full control in what happens. When
you know that the system works with browser you can trust that Mapserver side
is OK and you can continue to OpenLayers or other clients.

WMSGetFeatureInfo Javascript (OpenLayer)
var infoCtl = new OpenLayers.Control.WMSGetFeatureInfo({
layers: [_test],

queryVisible: true,

});
infoCtl.events.register("getfeatureinfo",map,showInfo);
function showInfo(evt) {
alert(evt.text);
}
I´m getting that :
