Safari will not display pages

Question

I recently updated to Mountain Lion on my late 2010 MacBook Air.  Today, I attempted to use Safari and I can get no page to display.  Safari itself loads, but no pages will load.  I use Chrome as my default browser and only pull up Safari occasionally, so I can't say for sure that I have used Safari since the upgrade, however, I probably have.
Today, I was invited to a Go To Meeting online meeting.  I opened the page in Chrome and it downloaded the GTM app.  I clicked on that and it tried unsuccessfully to download required files from it's server via it's own app.  I tried this several times without success and then thought to try the entire process using Safari.  That is when I discovered that Safari would not display pages.  It acts as if it has no connection to the internet.  Safari loads and the progress bar moves a little across the top then it just stops.  It never times out or complains; just nothing.
Given that the GTM app looks also like it cannot connect to the internet, I went looking at some of the suspects.  My firewall is turned off.  My network status comes up clean when I test it. ...and more oddly, Chrome seems to have no problems with any and all pages.
I searched for similar problems with solutions and one recommendation was to boot into safe mode to see if that made a difference.  I did that and there was no difference.  Since I don't use Safari routinely, it is stock, as delivered.
Any ideas for how to troubleshoot this?
Thanks,
Bill

Select  ▹ System Preferences ▹ Network ▹ Advanced ▹ Proxies. If any proxies are selected, deselect them, apply your changes, and try again. You must apply the changes before they take effect. You don’t need to change the other settings.
