problem in wordpress reader??

Are you all having it or only me?

When I am reading anything in wordpress reader, if I click the comment and post my comment in the reader often the comment is not sent to the blog. It happened to me for three or four days at a stretch!

When I am done writing the comment and press the back arrow to return to reader it takes me back to top of the list. can you imagine how annoying it is?

Every time, after posting a comment I have to scroll back down to the spot where I posted my last comment and resume my reading.

is it happening to me only?
