7.0.3 - In IE7, if you try to reply to a reply to a post in a member's Wall (2nd level of reply), that second reply disappears. Have not tested other versions of IE.
This does not happen in Firefox or Chrome. Went to the 3rd level of reply in both (didn't bother to test further). I then tried to view them in IE7 and nothing below the first reply will show up. (You can see it briefly and then it disappears.)
Looks like an IE bug. Can someone confirm this and post in Trac?
