Have ever happened to you that you were sent a document (.doc) from somebody using OpenOffice and you couldn’t add any comments and notes and stuff? Well, it happened to me some while ago and it took me a while to get it solved. It looks like some complex problem but it’s actually very stupid. At least, I felt stupid when I found out what is it about.
For some reason, OpenOffice when saving to .doc format they tend to lock the document. When you open it in MS Word, it results in having all the options on Revision tab grayed out. It’s all about one click to unlock the .doc, but that button is under another Lock document button, which is kinda confusing.
So, how you get there. You go to Revisions, then you click Lock the Document button and a sidebar pops up. It should say something like „Locked to protect the document from unwanted changes“. Look to the bottom of sidebar, there’s a small button Unlock Document. Hit it, and there you go.
If you have another experiences with this or something, just let me know in comments. BTW, I have only Czech version of MS Word, so the labels on buttons might be a bit imprecise. Take a look at pics to be sure.
