I'm testing btnp using the following snippet:

function TIC()
 cls(0)
 print(tostring(btnp(0,120,60)))
end

"print" function renders these things:

1. "false" on program start, key released;
2. "true" on the frame I pressed the key;
3. "false" for 2 seconds, key still pressed;
4. "true" for 1 frame, key still pressed;
5. "false" for 1 second, key still pressed;
6. back to item 4 until I release the key;
7. key pressed again, flows goes back to 2.

Is this the expected behaviour? Shouldn't step 2 return "false"?
