use "customize" and remove customization. Probably won't help. Search and find/download "tweakui" or "tweak133" and see uses, including restoring default settings.
When using Windows Explorer (Win98), it seems to operate okay when View settings of LargeIcons, SmallIcons and List. However, when I specify Details, no files or subdirectories display. It used to work ... anyone know what I am doing wrong?
