Strange Blogger/Google+ behaviour

Just a short notice for you out there: At the moment I am not able to comment on all your nice posts and stuff because I have some strange problems with the Google comments. They show me that I am logged in, I type my comments and send them and BAMM they are lost somewhere in the blogosphere.
I recall that Mr. Lee had this problem too some time ago, so if anyone of you reads this and has solved it, please hit me either by a comment or (if known) by an email.

Thanks in advance,
Paradox0n
