WANT your Windows 98 taskbar to have a cascading menu to all drives, folders, and files? Right-click the taskbar and select ToolbarsòNew Toolbar. Select My Computer and click OK. Slide the end of the toolbar to make it as small as Windows will allow. It will show only the words 'My Computer' and a small double arrow. Click the double arrow: You'll get a cascading menu. Open a drive or folder by right-clicking it and selecting Open or Explore. Open a file by clicking it.
