The trouble is that the PC was in a remote location (50 miles from the nearest town), most persons working in that place having a limited knowledge of PC. We presumed at that time some visitor, in prevision of loosing a maintenance contract, decided to write some *.* files. A user not very familiar with PC could try to erase those annoying files ... and the other files as well :-( We were lucky to discover this before damage :-) , but unable to find who make that. -- \_\ Denis Beauregard * internet:beaurega@ireq.hydro.qc.ca / \ Genealogiste officiel : Beauregard/Jarret/Jarest/Vincent J __> Vient de paraitre : Andre Jarret et ses Ancetres \_.-=== En vente par l'auteur Opinions ?
