I am running Win XP Pro and have noticed that Explorer is misbehaving. I have set the default view as Details but the only columns which are displaying details are:- Size, Date Modified, Date Created, Type, Date Accessed, Attributes, Status and Owner. All other columns (including Author, Title, Artist, Album Title, Year, Duration etc.) do not show any file properties at all. This is annoying because I mainly use Explorer to sort my music. When I right-click on an mp3 file (for example) and select Properties, if I click the Summary tab, there is nothing showing in either the Advanced or Simple views. Also when I hover the mouse pointer over an mp3 file all that is displayed in the hover-text is Type and Size - I'm sure more info was displayed before. I know that (from having previously organised/catalogued my music) all my music files have mp3 tags (these are displayed when I view the file info within my default mp3 player) so I am at a loss as to what has happened. I have uninstalled and reinstalled all software since I noticed this, and I have run Registry Mechanic just to make sure, but this has made no difference to Explorer. This is not an issue with column-widths. Is there a registry setting that needs to be tweaked/updated to rectify this?
