install rpm using yast

I like to stick to one method of installing software and upgrades/downgrades. so far yast has been pretty good about it. but lately when i right click on an rpm file and select "install rpm using yast", it does not want to work. somehow the dependencies window never pops up and i have to manually "rpm -Uvh......" putting the directory of the file in the yast installation source does not seem to have any effect. the os issuse 9.2-x64, downloaded from ftp site, up to date with "you". anybody seen this before?
