See my disclaimer and remember this worked for me, but no guarantee it will work for you.
I recently switched to a used Logitech wireless keyboard. After the Box started showing up, I also got a Caret Browsing F7 dialogue box when opening Firefox. Since F7 is also Office Spell Checker launch, I put 2 and 2 (or was it 3 and 3) and I went back to my old wired Dell keyboard.
Miraculously the problem went away and hasn't come back.
With regards to my disclaimer, even though it has been 3 months, it still applies!!
REMEMBER - HAVE OR MAKE CURRENT BACKUPS!!
IF YOU DON'T KNOW WHAT A BACKUP IS, YOU HAVE NO BUSINESS READING THIS!!
Today I started my machine first thing and everything was fine. I opened Word 2013, no problem. Fast forward to about 5 PM. I opened Outlook and tried to reply to an email. Tried being the operative word as the Spell Check Dialogue Box from Hell appeared. It would not let me close it or Outlook. I killed it with task manager. Then I tried Word (Yeah I know Outlook uses it as its WP). Same thing. Tried Excel. Ditto.
Suspecting maybe a hardware or driver error I tried a bunch of things. Nothing.
I researched on the Net - mostly useless.
Reviewed my event viewer. Found the Dreaded Event IDs 1508, 1502, 1515, and 1511 - User Profile problems. System Restore back to Patch Tuesday. Of course, System Restore errored out.
But magically it fixed my F7 problem. Spell Check had left the building (or User Profile).
Now, I DO NOT GUARANTEE THESE SUGGESTIONS. LET THE COMPUTER USER BEWARE!
So if that doesn't work for you, try creating an additional user profile, logging onto it, and try Word.
It just might work. But remember - HAVE OR MAKE CURRENT BACKUPS!!
In my new role as an unpaid Microsoft System Tester (therefore, I don't think I qualify for benefits), my disclaimer continues to apply.
Yesterday, a client complained that she could not get into her att.yahoo.com email. I found that whenever she went into Microsoft Edge or Internet Explorer 11, the browsers started flashing images and then became unresponsive. But only for att.yahoo.com (yahoo.com really). Other sites such as CNN.com and of course MSN.com (as in Microsoft Network) worked fine.
It may be a coincidence (yeah right), that the problem started with the ANNIVERSARY UPDATE. While I couldn't back out of the update because more than 10 days had gone by, I did back out of the August Cumulative Update and Behold - Edge started getting along with Yahoo. Imagine that.
Even with the regime change at Microsoft, my disclaimer really still applies, even if you can't find it way at the bottom.
Legend has that early on someone figured out for the telephone system to grow everyone would have to become a phone operator, which of course is what happened. We have also all become clerk typists and computer operators and bookkeepers and bank clerks and grocery checkers. Now Microsoft is trying to turn all Windows users into system testers. Something which Apple did a while back - but I think they are referred to as acolytes (look it up) not testers - think iOS 9, 9.1, 92., 9.3, et al. Kool-Aid anyone? Yeah, look that one up too.
I was a System Tester among other roles in my former life with what used to be called Pacific Bell. The purpose of the system tester was to develop scripts to follow during application testing based on what the software should or should not be doing. Then test using the scripts. If problems were found, the software got kicked back to the programmers.
Microsoft, in an effort to make even more money, has reduced their testing staff, replacing them with us. Unfortunately for all of us Windows system testers, it is difficult to kick the buggy software back to the developers and programmers.
Microsoft's Windows 10 Anniversary Update. I rest my case.
Regardless of where my computer thinks I live, my disclaimer continues to apply. If you don't believe me, just ask me.
My computer keeps insisting I live in zip code 94050, but that is some 50 miles away. A lot of folks have a similar issue. The very short answer is Domain Name Server (DNS) location. I am using the Google public DNS - 188.8.131.52 located in 94050. It is that simple.
Check to see if I have any typos in my disclaimer way below.
As soon as I posted about typosquatting belwo, my wife became a victim. She had transposed letters and typed craiglsit.com and got the dreaded " you are infected blah blah. Call 855-xxx-xxxx blah blah". It got past Malwarebytes. I tried OpenDNS and it got past that. Then I tried Whitelist Ninja, an add-in to Firefox.
Whitelist Ninja allows you to easily create a white list of sites you visit. The first time you visit a site, it warns you and lets you allow or block the site. It does require you set up a password, but if you are the only user, just set up a 1 character password for ease of use. Give it a try (at your own risk of course).
It, however, is not foolproof. If you insist on allowing a nasty site, it will let you. So, listen up and pay attention.
If you are from the New York Times or any of its advertisers, please see my disclaimer way down below. And please note that I am a a big fan of the First Amendment to the United States Constitution.
I just performed some tests using Chrome, Firefox, and Internet Explorer 11 using AdBlock Plus against nytimes.com. My definitely unscientific results show that Adblock Plus blocks the top banner ad (which I find really annoying). And while according to IE 11, it uses 0.29 seconds with Adblock Pro, the entire home page displays in approx 4 seconds, instead of 10 seconds or so with Adblock Plus disabled.
So my rhetorical question for today is, why as a paying subscriber do I get the banner ad for IBM or whomever, while users (I mean readers) of the hardcopy (paper) edition don't?
My inquiring mind would like to know.
