People experience it in syscons consoles with moused, as well as under X without moused. It will be great when its finally solved, but it's a real nasty one to solve. Personally I suspect it is due to nested or lost interrupts; unfortunately the PS/2 mouse doesn't have a proper framing protocol which makes synchronisation difficult if any data is ever lost. gram -- Dr Graham Wheeler E-mail: gram@cequrux.com Director, Research and Development WWW: http://www.cequrux.com CEQURUX Technologies Phone: +27(21)423-6065 Firewalls/VPN Specialists Fax: +27(21)424-3656 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
