this is a nasty one.  After using the ruler tool then activating the zoom in
tool, the function MapWmapTool gets called twice in succession (with only one
call to CWC2OnMouseMoveFunction).  I don't have a functional javascript debugger
right now so its impossible to trace, I'll try to work on this on another
machine that has a debugger.

The current workaround is to implement a quick check to ensure the function only
gets called once per CWC2OnMouseMoveFunction call ... this is not committed but
it works in my limited testing.  I'd like to try a debugger before settling on
this solution though.

To implement the workaround, add a variable at the top of MapDHTML.js:

var gMapWmapToolcalled = false;

in MapDHTML.js in function MapWmapTool add

if (gMapWmapToolcalled)
    return;
gMapWmapToolcalled = true;


in MapDHTML.widget.php in GetJavascriptOnMouseMoveFunctions() change to 

$szFunction = gMapWmapToolcalled = false;\n";
$szFunction .= "$szJsFunctionName(e);\n";

that's what I'll commit if I can't find a better solution.
