ADMIN does not use mod_rewrite for any of its URLs.
find the function `currentRelativeURL` in admin-functions.php and change it so it reads:
`
function currentRelativeURL($source) {
$source = str_replace('\\','/',$source);
$source = str_replace(SERVERPATH, '', $source);
$q = '';
if (!empty($_GET)) {
foreach ($_GET as $parm=>$value) {
$q .= $parm.'='.$value.'&';
}
$q = '?'.substr($q,0,-1);
}
return pathurlencode($source.$q);
}
`
I suspect this will fix the problem, but I do not have a Windows server, so cannot confirm.
