Sure it is not optimal. I was just wondering, how far we want to go in solving it - how bug the problem is. I still think redefining XMMP from the ground because of this is not the right way. -- The problem with graduate students, in general, is that they have to sleep every few days. Michal 'vorner' Vaner
