Weirdest thing. I use Netscape 7.1. Under the "Window" menu a list appears of active, open Netscape browser windows. For example, right now here's the lineup:
1 Tom Coyote Forums - Posting New Topic - Netscape
2 Address change - Inbox for Carolyn@ArtCalendar.com - Netscape 7.1
3 Google Advanced Search - Netscape
If I scroll to "3" I get Google. If I scroll to "2" I get my inbox. If I scroll to "1" I stay here. If I scroll to "4" I get absolutely nothing! As many as six or seven of these things have been up at any given time.
A system restart helps for awhile (a matter of an hour or several hours) then the phantoms start to appear again. Ditto for reinstalling Netscape.
