           Summary: MapDHTMLwidget occassionally fails
           Product: Chameleon
           Version: 1.99
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: critical
          Priority: P2
         Component: Widget
        AssignedTo: chameleon-dev at lists.maptools.org
        ReportedBy: bartvde at xs4all.nl

Occassionally the map in Chameleon displays a red cross in IE. Several users on
the user list have encountered this problem. Also, scalebars etc. sometimes
fail. This even happens on fast ADSL or in-house servers in my case.

I have tried to reproduce this problem using 1) a Python script and 2) a really
simple HTML page. The Python script loads a drawmap.phtml URL 50 times and none
of them fail. Only apparant thing is that the first load is always 4 seconds
instead of around 1,3 seconds.

The HTML page is really simple and reproduces the problem in my situation:

<html>
<script>
function load()
{
  document.images["bart"].src=
"/chameleon//common//wrapper/drawmap.php?map_session_mode=1&run_query=0&sid=4132c68f4bf7b&dummy=0.67554800+1093846677";
}
</script>
<body onload="load()">
<img id="bart">
</html>
