As soon as i press enter the box types on its own with repeated letters, sorry everyone
That's the keyboard buffer and those letters are your playing keys.
It happens when the FPS value is low or when there is a bad memory management (OS & browser).
Be sure you don't have other browser windows or tabs open (they eat your system resources for nothing).
Also (from time to time) check out the browser memory usage (in the Task manager).
If it's above 500 MB, close the browser and reopen it.
p.s.
During the game can you delete that crap with Backspace and type something decent?
If yes, that's a good sign.
I get a lot of jumbled letters like,eeeeeeeee or ssssseeeeekkkkk,etc when i type in the chat box during game-play,and the only reason i can think of is that my mouse arrow as moved out of the game screen,i have exited the game and returned to find it is still doing it,i am sorry about this everyone as it happens to me a lot,i am not able to say hello sometimes when players enter or much else,i don't know if any other players experience this problem or as often as me,i have zoomed the screen,and typed slowly,but i still get jumbled letters,hope no one thinks i am doing it on purpose,i have even tried to correct my mouse arrow and still the same. 
thank you for your help,i do use full chat all the time,and i will try the things you mentioned,i have had internet speed up to 50 from 20 since January,thanks.
works very well with the typing now except when the fps drop,so i keep my eyes on that and wait till it rises before typing, thanks for the hep Remus and freekarol
