# 3947 Mouse Enter/Leave Events Not Firing Correctly for Panels with Contained Controls Near/Over Border

---

Two labels on a TPanel. Label1 is fully on the panel, Label2 is either touching or slightly over the edge of the panel (and therefore a bit hidden).

The enter/leave detection works fine if you enter from the top, left or right. If you enter from the bottom, then you get the enter and immediately get the leave on the next move.

If I move the Label2 to be one pixel margin inside the panel, then it all works as you would expect.
