[horde] head: changes to layout don't take affect until next login

[Rob S.i.k.l.o.s.]

Hello,

Using latest Horde from CVS this morning.  I've had this problem for at
least a couple days - when I make any changes to the layout of my main Horde
page, those changes don't take effect (at best) until I log out and log back
in.

Rob.
