Hi Ben,

Could it be related to the "DnD code doesn't notice new windows" bug?

	http://bugzilla.gnome.org/show_bug.cgi?id=56349

I found this problem with ROX-Filer, which opens a new filer window if you
hold the pointer over a directory. Overlapping windows don't work
correctly because Gtk misunderstands the information about where the new
window is in the window stack.

The fix is trivial, but I don't know when it will get applied.
