Ok, it looks like this was using gvim. E.g., from the command-line, "gvim -o a.txt b.txt" gives me the same setup.

Since you said you clicked a button it sounds like you got this message in your gvim window, not your vim window.

What *should* have happened, is that your new Vim instance started within your terminal for diff mode, should have give you an error message about a swap file existing already, asking if you want to delete the swap file, open the file read-only, edit the file anyway, etc.

Since this did not happen, I wonder, what is running when you run "vim" from the command-line. On recent Windows, you can do "where vim" to find that out (similar to "which vim" in Unix). Also the :version command within that Vim could help.

On my system, the Cream installer for some reason created a "gvim.bat" and a couple others, but not "vim.bat". I had to launch "vim -d" with the absolute path to vim.exe.

When I follow all the same steps so far, I get the "swap exists" error message I describe in my vim diff, and if I answer "readonly" or "edit anyway" I get a diff window with file contents unchanged. File contents in gvim are also unchanged.

Disabling all plugins is done using "--noplugin" rather than "--no-plugin". I do that sometimes too :-)

Also try "gvim -d" rather than "vim -d" to see if that helps.
