I was messing around with my signature, and saw the option to upload a signature picture. I did this, and the picture displays correctly in the area for this, but when I try to insert it into my signature I just get the link text, rather than the actual picture. Any ideas what the problem is?

When I click the "Insert Signature Picture" link, it places these tags (without spaces)

[SIGPIC ][/SIGPIC ]

and this text appears in the actual signature,
