duplicates triplicates!!!!

[ANIKHTOS]

i am having this problem
i compose a message and then i click the submit button only to stay in the same page
so i click again and again just to realize that i am sending ti 2 3 times the same message

it does not happen every time
but it seems to happen when i compose a msg too long

and when i say too long i mean 10 min to hours (forget to submit the post)
thank you
