YaST2

For some reason when using YaST2 to configure a modem a sub window pops up with the words initialising then immediatly exits. I get an error message that y2bignfat has sementation faulted. This only appears to seg fault when configuring a modem. Digging down through the code (yast2 line 62) the arguments passed to y2bignfat are something like module (lan), arg2 (.modem), client (qt). y2bignfat works OK if arg2 is (.lan), but always fails if it is (.modem). I don't know where else to look now, I'm stumped. Can anybody help. (By the way I am using SuSE 7.2 and I know this used to work) I have re-loaded yast2 from the original suse disks but still have the problem. Regards, Phil Burness
