You'll have to use the mapping feature to cram that down to the 10 you want, if you have a device with more than 10 buttons. Try upping that to 20-something and rebuilding things and see what you get. If you get a panic, something's still amiss. -- Doug White | FreeBSD: The Power to Serve dwhite@gumbysoft.com | www.FreeBSD.org
