Now Trevor... my presence here, and any adivise I may offer, is strictly motivated by the most altruistic of reasons. OK? Now, Zimmy, if that's your real name, I pretty much described this in your first post back on March 1. It would seem you haven't gotten the air completely out. Work it slowly. Biff's got it right. (of course he was at a seminar I gave at SpriteSpree '03) Give me a call, if you wish, and I can talk you through it. Peter
