Event box bug?

[Nigel Gamble <nigel nrg org>]

I first reported this problem in GTK+-1.1.9.  The behavior is
unchanged in GTK+-1.1.12, and I didn't see any responses to
that report, so here it is again.  Can someone confirm either
that this is a bug, or that this is the expected behavior?

I'm using an event box to contain a checkbutton, but it seems to
badly affect the behavior of the checkbutton widget.  The test program
draws 4 checkbuttons.  "Button 1" and "Button 4" are inside event
boxes, while 2 and 3 are not.  When the cursor is moved onto
buttons 1 or 4, they are highlighted, but the highlighting is
not removed when the curor leaves the widget.  Similarly, the
"focus line" around buttons 1 and 4 is not removed when another
widget gains the focus.
