En gros et en français :Mozillazine a écrit : Dataloss Bug in Latest Windows Installer Builds Can Delete Contents of Program Files Folder
A serious bug in the latest Windows installer builds of the Mozilla Application Suite can lead to users having the entire contents of their Program Files folder deleted. The problem is present in the 2004-02-03-18 and later trunk Windows installer and net installer builds. The affected binaries have had the suffix -dangerous added to their filenames and been removed from the latest-trunk and latest directories on the mozilla.org FTP site. Testers are strongly advised not to download these dangerous builds. The issue is being tracked in bug 233014 (please do not add unnecessary comments to this bug). Thanks to Zbigniew Braniecki for alerting us to this problem.
ne pas essayer d'installer la Suite Mozilla fournie depuis le 3 février, car il y a un risque de suppression de toute l'arborescence "Program Files"
Ce doit être corrigé dans les versions à partir d'aujourd'hui (les versions bugguées ont été renommées "xxx-dangerous" sur le site officiel)
