[newbie] kppp.pid file error?

[DRX]

     When I click on the "Internet" icon in KDE, I get an error message
saying that kppp has detected a kppp.pid file.  It also tells me that
another instance of kppp seems to be running under process-ID 803.  It
tells me to delete the pid file and restart kppp. I can su to root and kill
process 803, but this error ocurrs every time I log in as this user.  How
do I stop this error from recurring?

                        Thank you.
