When viewing a section (of a chapter) of my project (thesis) in scrivenings mode, it crashed twice after highlighting text.
I highlighted a section of text I wanted to copy to another section of the chapter. In this case it was from a sub-section, and I copied by highlighting and pressing ctrl+c. Still in scrivenings mode, I then inserted the cursor in the text of the main document (i.e. the one that the sub-section was a sub-section of, so this is my introduction to the following sub-sections) and pressed ctrl+v. It pasted the section. I then highlighted the quote again, thinking to change the font. Scrivener crashed. I also had dropbox running the background uploading something, and I am editing my scrivener file directly in the dropbox folder.
I closed scrivener, reopened, did the same thing. Fine.
THen I highlighted the quote I had just copied, changed the font. Fine.
Then I moved up a level, so scrivenings mode was open for the whole chapter and not just the section I was working on. I highlighted the text in the main document again (the introduction to the whole chapter) and tried to change the font. Scrivener crashed. Dropbox seemed to have finished its task then, but I was still running from the dropbox folder. (not sure if this is relevant or not!)
