To reproduce: 1) create a read-only file $ create a.txt [ctrl-z to end input] $ set file/prot=o:r a.txt 2) edit with vim - it is opened as [RO] $ vim a.txt 3) enter insert mode i vim shows a warning message (W10: Warning: Changing a readonly file), and then displays [+][RO] 4) type something; press Ctrl-X (the first part of Ctrl-X,N) hello<C-X> Result: Upon pressing Ctrl-X, vim deletes the whole line (the "hello" word). Expected result (observable on Windows): Upon pressing Ctrl-X, vim waits until N (to complete Ctrl-X,N), then offers suggestions. =================== Other notes: I also got this behaviour in a writable file, but a read-only, edited file (with [+][RO] had to be loaded in another buffer (or window?). I only managed to get this behaviour shortly after editing the read-only file. (Of course, this observation may be imprecise. It certainly seems strange.)
