What kind of problems. Please provide more details.
I use OpenSUSE 11 and I have never had problem with DualBoot. Sometimes I used 3 systems (2 different windows versions and Linux). GRUB was always configured automatically and if not then was very easy to configure it with YaST (SUSE specific configurator).
Please provide details about your disk (partitions) and GRUB conf (/boot/grub/grub.conf)
