My responsibility is developing repository for my company in moodle 2 version. My environment is windows server and I used both IIS and apache in my testing environment for moodle 2.
My problem is when I go to my http://webaddress/moodle/course/editsection.php?id=1 page in Internet explorer version 6, 7 and 8 for editing the content; every time browser goes to response out when leaving this page but at time same time for firefox working fine.
I think this is major bug for current release of moodle version 2.0 dev (Build: 20090407). I got this error in all Moodle 2 version.
