[Chameleon] selectbox vs MapDHTML in IE

[Paul Spencer]

That bug refers specifically to the QuickZoom widget but this is a class 
of general problems with IE.  You have a couple of choices:

1. move the select box ... not optimal but it will work

2. add onfocus/onblur handlers to your select and temporarily unset the 
form variable NAV_CMD. I.e:

<script type="text/javascript">
var myNavCmd;

function myFocus()
{
     myNavCmd = document.forms[0].NAV_CMD.value;
     document.forms[0].NAV_CMD.value = '';
}

function myBlur()
{
     document.forms[0].NAV_CMD.value = myNavCmd;
}
</script>

<select onfocus="myFocus()" onblur="myBlur()">
...

(note code not tested but should work)

3. try to add something to the onchange that prevents event propogation 
... this is tricky and is the root of the problem - IE and firefox 
propogate events in different ways

Cheers
