this may sound like a stupid problem to have, but it bothers me for some reason. the category headings are missing when I open 'My Computer'. there should be headings in bold such as: Files Stored on This Computer: Hard Disk Drives: Devices with Removable Storage: they are not there for some reason. i've tried every different view, tried switching to classic folders and then back to 'show common tasks'. can't figure out why they disappeared or how to get them back.
