[Orgmode] I need help about org-mode with auto-fill-mode

[Meteor Liu]

Hello,

I used auto-fill-mode in org-mode.
for turn off TeX-like syntax, I add "#+OPTIONS: ^:nil" to the head.

I input some words, for example, "test test test ......", 
when the length over fill-column, the second line becomes 
"#test test ...", I don't want get the "#". 
Any suggestions?

I use emacs23.1 and org-mode 6.21b in Windows XP.

Regards,
Meteor Liu
