Woody and X not liking xhost +

[Hanasaki JiJI]

I am running woody and have two shells open in X.  One is su'ed to root 
and has the display variable set correctly and exported.  The other is a 
common user id that has done xhost +.

When I run an X program from the su'ed shell I get an errot "cannot 
connect"  It looks alot like it would if I had not done xhost +.  Any 
thoughts?

Oh, the exact same procedure did work under potato

Thanks.
