Check out the helpfile:

GUIGetCursorInfo ( [winhandle] )



winhandle [optional] The handle of the window to use. If omitted the "current" window will be used.


Return Value


Success: a five-element array that containing the mouse cursor information:
    $aArray[0] = X coord (horizontal)
    $aArray[1] = Y coord (vertical)
    $aArray[2] = Primary down (1 if pressed, 0 if not pressed)
    $aArray[3] = Secondary down (1 if pressed, 0 if not pressed)
    $aArray[4] = ID of the control that the mouse cursor is hovering over (or 0 if none) Failure: sets the @error flag to non-zero.


So you can check the array, like suggested, or check the @error
