[newbie] Weird problem

[root]

Hi,

I have a question for when I log on. Once kppp logs on to my ISP, I
can't open the browser or ANY other program. This occurs as the root
user and as a normal user.

If I open a program BEFORE I log on, I can continue to use the program
normally. However, I can't open any program that wasn't aleady opened
before logging on.

Thanks,

Sam Walker
