What other commands do you have in your .vimrc to enable the undo file for other file types? I'd guess you have an interference going on. It's probably not related to your current problem, but you probably also want a BufNewFile autocmd event in there. Also, why are you using "setlocal undolevels=-1" instead of "setlocal noundofile", if you goal is only to disable persistent undo? Setting undolevels to -1 disables undo *entirely*, not just persistent undo, so that pressing 'u' in normal mode while you edit will do nothing. -- -- You received this message from the "vim_use" maillist.
