unable to comment to flickr in my group room

Since the maintenance yesterday, I have been unable to post comments to flickr from our group room (365 - DPS assignment). The comment pop up appears and I am able to type my comment but when I click the round button to send, it disappears without posting my comment to the room and my comment does not show up in flickr. Help! Thanks! I tried this in the photophlow room and it worked ok, so am now really puzzled.
