EventReceive catches events so fast

[keynet]

Hi.
I made a simple chatting program, and it gets key inputs using IEventReceiver.

When event.KeyInput.Key is irr::KEY_RETURN and event.KeyInput.PressDown is set, the program send chat message to sever and clear the edit box's text.
And it checks this event while dev->run() which of FPS is set to 30 FPS.
Also when the chat message is empty, it shows a messagebox that should be something on the chat message edit box.

However, the program gets user's Enter Key event so fast, so even I put some message on edit box and input Enter Key, it tries message at least twice so that the first message sent and the second cleared-message isn't sent, which shows a "edit box is empty!" message box.

Why does IEventReceiver get user's key input so fast?
And is there any method to control this speed so that I can get user's input not so badly fast?

Please help. Thanks in advance

The event is only sent once, and key repeat is not that fast that it would occur on a single key hit. Maybe you just check the key state? In that case, you might get more than one frame with state key pressed. Maybe show your code?
