Please apply. As to Guennadi's problem with colours and images, I've been trying to reproduce locally without success, hence silence. My pm2fb-on-Sparc correspondent hasn't seen this either, and I've had no other reports. I have one possible clue, which I'll pursue with Guennadi off-list. --=20 Jim Hague - jim.hague@acm.org Never trust a computer you can't l= ift. ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
