I was messing with the TOOLS / Internet Options / Browsing History / Settings

On that page I selected, under Temporary Internet Files, I changed the setting under 'check for newer versions of stored pages'...from automatic to one of the other settings, I cannot recall if it was never, or one of the others,

So, yes, do not do what I did....and no, I haven't gone the non-microsoft route yet...but I probably should....
