Re: Perl Prog as Root

Tom,

You can also use xauth. Be careful with xhost as you can open you machine up
to outsiders if you don't know what you are doing. I had a similar problem 
many moons
ago when I was trying to bring up a tk app as root. Don't remember full 
solution but I used
xauth. I basically googled for xlib warning generated by firing up tk app. 
This gave me many
things to try. So you might want to do the same.

Regards,

Mike
