Mouselook function issues(on OSX)

Allright, it came upon me the time to code(as all the ones i tested were laggy on OSX) a mouse look function, currently it is as following:

		# get cursor position(pyMouse not mouse sensor)
		mouse_x = round(self.mouse.position[0],2)
		mouse_y = round(self.mouse.position[1],2)

		# check if user want mouse movement inverted
		if self.mouse_invert_enabled == True:
			mouse_invert = -1
		else:
			mouse_invert = 1

		#Verify if mouse is still moving from its last position
		if mouse_x != self.mouse_old_x:
			mouse_dif_x = (self.mouse_old_x-mouse_x)*mouse_invert	
			
			self.player_col_box.applyRotation([0,0,mouse_dif_x], False)

			#store a "previous mouse position" before another loop
			self.mouse_old_x = mouse_x		

		#If mouse stopped moving(mouse_old_x = mouse_x) and isn't at screen center
		elif self.mouse_old_x != 0.5:
			# Center mouse in game window				
			render.setMousePosition(self.screen_w//2, self.screen_h//2)

The problem with the above code is which when mouse_dif_x is 0(after a cursor reentering in the screen), the player collision box return to 0 rotation(I thought if it was 0 nothing would happen); what I wanted was to add the mouse_dif_x value to the object Z axis value, not for it to be the object Z axis value; so how could I code that?

Thanks for any help

Uh, sorry, my fault gentleman: when the mouse was recentered to the center screen I forgot to set mouse_old_x to 0.5(screen center), so when the mouse moved again it would take as mouse_old_x the mouse position outside the screen center; and as the mouse_old_x was greater(or lesser) than the reentered mouse position the applyRotation would subtract the rotation which was done previously(if previously the mouse was greater than 0.5) or add the previous rotation(if it was lesser than 0.5); effectively canceling the previous movement.
