I viewed the tutorial on FCK editor skins and tried to download two skins from SourceForge.net as instructed. However, I could not extract the files because Vista says they are "invalid" and Windows XP says they are "corrupted." The link to SourceForge is on the page that summarizes the training. Has anyone else had this problem? I was trying to install the Office 2007 and Aluminum skins for the FCK editor.Carol Langdon
