I think I know the answer. But I'll ask anyway.
Is there any chance that you made a remaster of your KDE 3 system when it was set up the way you liked it?
If so, boot that disk and see what process was called when you did your conversions.
This is a case that shows why all of us who are getting ready to install PCLOS 2010, might want to do a remaster NOW.
There are functions on an old comfortable system that we have long since forgotten that we added to the base system.
It is a lot easier to find a KDE 4 replacement for a known KDE 3 package than it is to find a replacement by function.
No, I really don't mean this as one of those "hey dummy, YOU SHOULD HAVE DONE THIS" posts.
I know that there are people who have not converted who soon will who are following your threads.
