As I write this, I have 9 mail items, 7 of them Energy Credit spam. I select the check box with each message I wish to delete, hit delete, and it just clear the checkboxes. The mail is still there. I've recorded this happening repeatably in PSR (Problem Steps Recorder) which is a Win7/Server 2008 utility, then I noticed the "attachment" ability is no longer present in these forums, sad. I can send it if someone needs more proof of this bug.
