Yast conflict resolution question

Hi. I have a 9.1 system working great. I want to install a package ("A") that I haven't installed before, so I go to Yast and try to install it. When I select "A", I get dependency errors because in the meantime You has upgraded package "B" that "A" depends on. Yast will let me downgrade "B" (which isn't such a good idea because "B" is all configured and customized) or install "A" and ignore the conflict. What is the best way to overcome the situation? There is an upgraded package "A" out there on the update server. Why won't Yast go get that one? Thanks!
