Yep, I got the same problem when using pon to connect.

As I stated beforehand, browsing the web using konqueror webprofile is not a problem, it's when I try to browse my files on my local hard drive with konqueror filebrowsing profile and I have a pppd connection.

I'll summarise:

1) When connected to the net using a pppd connection:
- Konqueror in webprofile works normally
- Konqueror in filebrowsing profile takes approx 4 mins to appear on my screen after launching it.

2) When there is no pppd connection
- Konqueror in webprofile works normally
- Konqueror in filebrowsing profile works normally, (loads in about 1-2 secs)

I have also noticed that when establishing a pppd connection before starting X and loading KDE, KDE will takes about 4-5 mins to start. (Unlike the normal 15-20 secs it takes when there is no pppd connection)

It looks like KDE is trying to poll for something when there is a network connection established. Just wish I could figure out what....
