Discovered the "navigation toolbar" wasn't displaying in Netscape (the long bar that lets you type in a URL and/or shows you the URL of the site you're on). After some fussing about (complicated by my not knowing the name of that specific bar), I found the solution:
From the menu at top of screen, click on "View" and then from the dropdown menu on "show/hide." If "navigation toolbar" (the first entry on the dropdown) doesn't have a checkmark in front of it, the toolbar is hidden. Check the entry to un-hide it. / Denny
