Widgets disappear when shrinking browser

I have created a site at rickwinston.org and when I shrink the browser in to see how the site works as a responsive site, the plain text/html widgets I set up, disappear. I haven’t had this problem before. I’m using the Baskerville theme and I tried deactivating all plugins, but it still didn’t work. Another issue is that changes made in a widget wouldn’t show up when viewing the site in Mac Safari and Firefox and Windows IE. They did show up in Chrome in both Mac and PC, and in Firefox on a PC. I would like to use Display Widgets, but turned it off for this troubleshooting. Any help would be appreciated.
Thanks,
Andy
