# 3643 Container Controls Firing OnMouseLeave When Mouse Enters Child Control

---

When I put a TLabel on a TPanel and used OnMouseEnter and OnMouseLeave to change the color of the panel in the prerelease version, OnMouseLeave of the panel was not fired when the cursor was inside the panel and entered the Label. Now that's the case. I can assign OnMouseEnter to the label as well, but there may be some flickering because of that.
