Launched 5 secs. after that worked nicely. Also, pppd acts strange. Also, timidity. Also some simple svgalib apps from /usr/games. What may be the cause of such behavior? How to get rid of this? I suppose my RAM is functional. -- /* Michał Pasternak, http://pasternak.w.lub.pl, +48606570000 */ /* www.anti-dmca.org, www.debian.org/devel/debian-med */ /* On the first day God typed "M-x create-world". */ -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
