Mouse Broadcasting issue

Hello
I am using this code for mouse broadcasting and most of the times when i broadcast, my mouse cursor jumps to another game window which results to accidentally move my alts and the whole thing gets messy. any reason why this happens ? is there a solution?

Code:

---

//-----------------------------------------------------------// BROADCAST MOUSE CLICKS. HOLD DOWN OEM3 (ON U.S. KEYBOARDS,
// THAT'S THE SQUIGGLE KEY IN UPPPER LEFT CORNER) WHEN YOU
// WANT TO BROADCAST.
//-----------------------------------------------------------
<UseKeyAsModifier Oem3>


<Hotkey ScrollLockOn Oem3 LButton, MButton, RButton, Button4, Button5>
  <PassThrough>
  <SendLabel w2,w3,w4,w5>
      <ClickMouse %TriggerMainKey%>
