Recently, a problem has appeared that I never had had on my computer. Take a link, no matter how harmless (http or https), and put it into a Word document (Microsoft Office Word 2007, running on a PC with Windows 10). It appears in blue and underlined, as usual. Now put the cursor on it, press Ctrl and click: until recently the link appeared in a browser. But now I get a message saying "The operation has been canceled due to restrictions in effect on this computer." Take the same link and put it in the address window in a browser, and the site comes up, no problem. So it would not be an ad-blocker or anti-virus function, I believe. Between when the function Wordlink-Ctrl-Click worked and when it didn't work, no new programs were added or subtracted from the computer. I am not sure how to even start looking into the problem. (Note that I am not a programmer, so that I cannot delve into the underlying programming of Word.) Any hints or suggestions would be appreciated.
