X not allowing local connections?

[Jon Schewe <jpschewe@eggplant.mtu.net>]

Lately I've been noticing that if I leave X up a week or so after a while X
'forgets' who has permission to connect to the server.  By default the DISPLAY
variable is set to :0.0.  But I can't connect with my display set to that, or
localhost:0.0, I have to use eggplant:0.0.  This means that none of my root
menus work and I have to set the display in an xterm then start apps from
there, or logout.  Has anyone else seen this and have suggestions?
