Sorry, no clue what a windows live account is, let alonehave one.
Pretty well described what is happening – others have too.
Basic is that the quick post – and the other post – and thereply to PMs lock up when you push the button to post them.

Only way to beat it is to type it up on word, copy it, pasteit VERY quickly, and hit the post button. Then, sometimes, it doesn’t lock up. It does randomly run words together after the post button is hit. They paste as typed, but after pushing thepost button they clog up here and there.
