Hi, this is mystery to me. I have restarted Windows and retested and now diff in vim works without a problem.
I don't understand what was wrong before. But I both files were marked as completely different - both windows in red background. In my humble opinion there must be some strange bug or something that I can't reproduce anymore. Regards -- -- You received this message from the "vim_use" maillist. Do not top-post!
