using uddeIM integrated with CB...
i seem to be having an issue where users get a "404 - component not found" error when replying to messages. its fine when a new message is composed and sent. it only happens when a user replies to a message. and its not specific to any one user account, it seems to affect all of them.

i have search engine friendly urls turned off already. and no other component on the site is causing a 404 error, its just this particular instance.

any ideas?
