XP orders files backwards

XP orders files backwards

Windows XP sorts everything alphebetically by name, except that it does it backwards. As it folders are always at the end and then ordered from Z-A. This is not only in Windows Explorer (which is easy to fix via the sort option) but also in dialogs when I click to browse for a file. For example in Firefox, when I click to upload a file, it shows everything ordered from Z-A and I need to move to the end to move to the next folder.
