issue with the MS Windows explorer views

[aromes]

In any windows explorer window, from the menu "View" | "Explorer Bar", I can have

"Search" and "Favorites" displayed on my left with no problem. But when I choose "Folders" in order to display folders on my left pane, I get a grey window instead

(all the left pane is greyed out). I have that problem with all user profiles I use on that computer. Deleting my user profiles and accessing MS Windows 2000 with freshly redone windows user profiles wont solve the problem.
