Same with fvwm-2.4.8.
I've discovered that HandleEnterNotify() is only called with Netscape's
"frame" window in this situation, not with the real window. Output from
a fprintf() at the beginning of HandleEnterNotify():
ewp->window=0x8000a0, Event.xany.window=0x8000a0, Tmp_win->w=0x14003ae
If the pointer was inside the transient "Find" window before closing it:
ewp->window=0x8000a0, Event.xany.window=0x8000a0, Tmp_win->w=0x14003ae
ewp->window=0x14003ae, Event.xany.window=0x14003ae, Tmp_win->w=0x14003ae
If the pointer is moved onto the title bar:
ewp->window=0x8000a1, Event.xany.window=0x8000a1, Tmp_win->w=0x14003ae
I've no idea what this Tmp_win->frame window is, or why there is sometimes
one EnterNotify event and sometimes two. But changing
Event.xany.window == Tmp_win->w
to
Event.xany.window == Tmp_win->w || Event.xany.window == Tmp_win->frame
near the end of HandleEnterNotify() seems to fix (or work around)
the problem.

This bug is still there, even in fvwm-2.4.8 with the workaround I've
found.
