Getting Rid of Blue Squiggly Underlines

@clan kinraithe: it is there (albeit greyed out), 13th checkbox from the top, just under "Keep track of formatting".

I agree about the pop-up though, and I don't like the anomalous behaviour of its 'Close' link, which doesn't change the cursor to a hand-with-pointing-finger like all normal links do.

Your screen shot doesn't actually show an example of the "Mark Formatting Inconsistencies" check box. I presume it must be there some place, but the example would be more clear if the specific box was shown.

Also, you don't need to always put that "subscribe" pop-up in front of the articles whenever I open the webpage, or return to it after looking at something else. If I want to subscribe, I'll find the link. That pop-up, like all pop-ups, is just annoying.

Thanks. Got me on the right track. File/Options/PROOFING/"Mark grammer errors as you type"

@Kris: if unchecking "Mark formatting inconsistencies" didn't make the blue lines go away, you're probably seeing the same behaviour as I noted in my comment two below yours. Grammar check errors and contextual spelling errors are also marked with blue squiggly lines, and in that respect this Word Tip is out of date. Try going to Word Options -> Proofing and unchecking "Mark grammar errors as you type", and maybe a few more of the options there, if that doesn't work.

That did NOT work. The blue lines won't go away!! Is there a way to change the rule? I don't want words capitalized. I am showing words and definitions for students and don't want them to think all the words are proper nouns. Who made WORD the grammar nazi???

You can remove the blue squiggly lines by unchecking the "Mark grammar errors as you type" under the "Proofing" options.

For me, this tip is only partly correct - yes, if enabled, formatting inconsistencies are marked with a blue squiggly line but so are grammar check errors and contextual spelling errors. I have "Mark grammar errors as you type" turned on and "Mark formatting inconsistencies" turned off, and I see blue lines but never a green line in Word 2013 and 2016, so I think this part of the tip is out of date. See for example http://www.gcflearnfree.org/word2013/checking-spelling-and-grammar/2/ which states "In previous versions of Word, grammar errors were marked with a green line, while contextual spelling errors were marked with a blue line".

@robert wyatt: in my Word 2016 (on Windows 7) the "Mark formatting inconsistencies" check box is a sub-option under the "Keep track of formatting" check box, which is the 11th main option under "Editing options". It is greyed out if "Keep track of formatting" is unchecked.

This explanation is hard to follow, at least for people with Windows 10,because it says, "In the Editing Options section, clear the Mark Formatting Inconsistencies check box." But there is no Mark Formatting Inconsistencies. Look as long as you like. It's not in mine, anyway. But if you hit every button, you might get lucky.

Thank you very much, it helped!
