OK, i do have some parallel install (but not exactly same versions of softwares since most are beta and one is a official install). When my bench will done, i'll share if you wish :-) Stef _______________________________________________ PLF-discuss mailing list [email protected] https://www.zarb.org/mailman/listinfo/plf-discuss
