fonts for openoffice

Hello everyone, you don't have to help me out on the hebrew fonts stuff I was dealing with. I managed to make them work in Abiword so now I'm using that. That's all I need. But in case a mystery (to me) wants to be solved here, how can a group of fonts, correctly installed with a reliable rpm, be legible in Abiword, but not in Openoffice Writer? (whether I use KDE or Gnome.) By the way, I like Abiword for a change now and then. ^^ Greetings Herman
