I used Fireworks 8 to build a navigation bar and imported to
Dreamweaver 8. Each button points to a different frameset. All the
links work fine except when, after clicking the first button and
clicking the browser back button, the first button then shows a
white rectangle. Clicking on the white rectangle still links to the
right page but the button is gone. This is true using Safari and
Firefox but the problem doesn't show in IE7. All the other buttons
work fine in all browsers. What the hey???
