Status: RESOLVED INCOMPLETE

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4b) Gecko/20030516 Mozilla Firebird/0.6

In GIS-maps on the web a common function is to be able to select and magnify a
portion of the map. This is normally done by selecting the approprioate function
(in the demonstration URL this is the second icon on the top left) by a
mouseclick. After this the mouse can be used to click-and-drag a selected
portion of the map. MozillaFirebirds cursor, however, changes to a leaflet and
moves back to its original position without the desired result.

Reproducible: Always

Steps to Reproduce:
1. Select the URL
2. Click on the second icon on the top left (with a magnifying glass on a square)
3. Click anywhere on the map, hold the mouse button and drag to another place on
the map.

Actual Results:  
The cursor moves back to the first position in step 3, changing to a leaflet in
the process.

Expected Results:  
Signal the mouse-coordinates of the selected square to the URL-server.

Same behavior in Mozilla 2003062708, moving to Browser component.

Site is throwing a number of JS errors:

Error: vspc is not defined

Error: theObj has no properties

I'm getting a similar problem:

Mozilla/5.0 (Windows; U; WinNT4.0; en-US; rv:1.5a) Gecko/20030629 Mozilla
Firebird/0.6

- the cursor turns into a crossed circle (/) symbol.

[Hermann Schwab]

removed comment "(and many more)" from URL, this made the link notworking.

My uneducated guess is the culprit is the browser checking code in

http://geodata.prv.gelderland.nl/km/ndtsubsidies/zoom.js

	// Variabelen voor browsertype
	var isIE = false;
	var isNav = (navigator.appName.indexOf("Netscape")>=0);
	var isNav4 = false;
	var isIE4 = false;
	var is5up = false;

	is5up = true;
	isNav = true;
	isIE = false;
	isIE4 = false;
	isNav4 = false;

	var isIE = false;
	var isNav = (navigator.appName.indexOf("Netscape")>=0);
	var isNav4 = false;
	var isIE4 = false;
	var is5up = false;

	if (isNav) {
		if (parseFloat(navigator.appVersion)<5) {
			isNav4=true;
		} else {
			is5up = true;
		}
	} else {
		isIE4=true;
		isIE=true;
		if (navigator.appVersion.indexOf("MSIE 5")>0) {
			isIE4 = false;
			is5up = true;
		}
	}

This is so a tech evangelism bug. Well it looks like, when you see comment #3.

When you want to see lines that bug (by clicking on it in JS console), you go to
this :

(for line 409)

"function getLayer(name) {
		// Terug geven van de layer(name)
      	if (isNav4)
        		return(document.layers[name]);
		else if (isIE4) {
			if ( eval('document.all.' + name) != null) {
				layer = eval('document.all.' + name + '.style');
				return(layer);
			} else
				return(null);
		} else if (is5up) {
			var theObj = document.getElementById(name);
			return theObj.style
		} else
			return(null);
		}"

and this (for line 478)

"function clipLayer(name, clipleft, cliptop, clipright, clipbottom) {
		var layer = getLayer(name);
		if (layer != null) {
			if (isNav4) {
				layer.clip.left   = clipleft;
				layer.clip.top    = cliptop;
				layer.clip.right  = clipright;
				layer.clip.bottom = clipbottom;
			} else if (isIE) {
				layer.clip = 'rect(' + cliptop + ' ' +  clipright + ' ' + clipbottom + ' ' +
clipleft +')';
			} else {
			layer.height = clipbottom - cliptop;
			layer.width = clipright - clipleft;
			layer.top   = (cliptop+vspc) + "px";
			layer.left  = (clipleft+hspc) + "px";
			}
		}
	}"

This site thinks Netscape can only be a 4.x one. So this site thinks we are
still in 1997-1998 !

INCOMPLETE due to lack of activity since the end of 2009.

If someone is willing to investigate the issues raised in this bug to determine whether they still exist, *and* work with the site in question to fix any existing issues, please feel free to re-open and assign to yourself.

Sorry for the bugspam; filter on "NO MORE PRE-2010 TE BUGS" to remove.
