Oh, I saw your posting to the list. It's in my inbox, along with many other emails I'd like to respond to over the next few weeks. Nothing personal, I'm just too busy right now to deal with your ongoing daily list of questions. Please post all your questions to the ML and people will respond when they can, if they can. -- Steven Toth - Kernel Labs http://www.kernellabs.com
