When I type sentences via chat application there's a bug.
I type a sentence like 'hello my name is AA and nice to meet you" and press 'send' button right side of the text input box.
And then directly type another sentence like "when can I...."
Then "you" the last word at the previous sentence is automatically appear on the text input box. "you when can I..."
I think the buffering or delaying cause this problem.
