Is this problem coming from my parameters (weight, prio, ...) or is it a known problem with CBQ ? regards, ------------------------------------------------ Franck BALAZOT (fbalazot@aeta.fr) AETA.COM 361, Avenue du G=E9n=E9ral De Gaulle 92140 CLAMART FRANCE T=E9l:01.41.36.12.93 ------------------------------------------------ _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://ds9a.nl/2.4Rout= ing/
