Can I check a document?

a document hangs the program constantly when I’m working and moving in it.
I’m working with Windows 7, LO Version: 6.0.6.2, format .odt but also .doc .docx
But if is not possible to check the document and correct it in W7, but in linux, I could do it too. I think, my problem occurs when I insert pictures bigger than the space to the bottom of the page. Then the document become unstable

My favorite fortune teller is not available presently to guess your OS, LO version and document format (.doc(x), .odt or else). Provide more information with an edit of your question, not an answer.

It is possible that part of your problem is caused by frequently changing the format of the document. It is recommended to always work with documents in LO’s native formats (.odt for Writer) and to always save them as such. Save as .doc or .docx only when you need to share the document with someone else. Might that apply to your situation?

Have you tried splitting your document into smaller chunks, and see which chunk is causing the bother ?
If pain persists, keep halving the document until you find all the offending element/s.

And what is the question actually? Read these guidelines and ask a good one.

The question remains the same: Can I check a document? I want to check a document to fix it. I was only answering the comments that made some people, to be clear. I don’t know exactly what you mind. I’m sorry if my question is not a good one.

What do you mean by “check”? Do you want to have a look at its internal representation to see if it is conformant? Do you want somebody else to criticise your work procedure and detect anomalies or non standard use of Writer? Are you looking for a method to validate your document yourself? (in the latter case, see @BrianRoper’s excellent suggestion)

If your document opens in LibreOffice then it is a valid ODF document. There is hardly anything else that you can do to check it (meaning an entire document). And yes, BrianRoper’s suggestion is good. Once you have found a problem item, you can see if it always causes problems. In such a case, this might indicate a bug in LO itself and be a good reason to report a bug.
