Are you on dial-up and using an outdated version of Internet Explorer? I've ran in to some slight problems with the code on older computers running IE 6 or lower.
A quick solution is to just register, that removes the code entry blank.

I have had this happen, too, and I found if I hit "PREVIEW" first,and then post, it usually doesn't do that and of course it doesn't hurt me to preview it anyway. Just an idea!
