A search didn’t turn up anything related to this. I downloaded Scrivener a few days ago, and now I’m in the process of trying to get my story set up to work on in it.
I saved the Word files in RTF format to import, and was able to import a couple all right, but every time I tried to import one of them I would get a message that Scrivener had stopped working, and I had to close it. I tried several times, until it finally occurred to me that the difference between that file and the others was that it had bullet points in it (no special characters, just a dash to start out each point).
After I went through and undid all the automatic bullet points, it uploaded alright.
