Possible chat bug.

Okay so, I don't know if it is just me...maybe it's others, who knows. I also don't know if this effects say chat at all, but I do know this has happened to me in Linkshell, party, and whisper. Whenever i type an exceedingly long response, ive noticed my friends just don't receive the message. Naturally I renter it..same deal. The weird part is this is entirely hit and miss, some responses go through, others do not. This also only applies to posts greater than half a paragraph. My friends have also done similar things and I have no recieved THEIR messages from time to time. Needless to say if I am role playing with my friends this lack of communication is incredibly stressful. Perhaps it isn't even a bug, maybe it is something I am typing? A little bit of light on the situation would be magnificent, please and thank you =)
