BgRegister X server insecure - newbie

Hi,

I am sure this has been covered before, but I cannot find a fix.

I keep seeing these msgs:
 BgRegister X server insecure (must use xauth-style authorization);
 command ignored

 exmh-bg cannot rendez-vous with UI - exiting.
 Usually this is because Tk send is not working.

I looked at FAQ 4b, but I am still not sure what to do. Can anyone help?

exmh version 2.6.3
os: aix 5.2

thanks.....
