SuSE 8.0 & CUPS

Hello, I have a big problem with the CUPS-Modul of Yast. I installed tow times SuSE 8.0 today, all worked fine. But if I changed from LPD to CUPS with YAST2, I becomed some problemes. SuSEconfig with LPD need a minute for all. But SuSEconfig with CUPS need a minute for each task of SuSEconfig, that means more then 10 minutes. I don't understand this. Why is this so? Thanks for help Patrick
