I have these commands in my ~/.vim/filetypes.vim file:

au BufNewFile,BufRead /home/cts/nodes/f0/test/find/* call DetectFind()
And it works fine when I start up vim - if there's a vim file with the same
root as the file I'm editing, it'll colorize it.
The problem is, if I switch buffers and come back, it doesn't colorize - I
suspect that DetectFind() isn't being invoked again.
I've looked at all kinds of things, did_filetype, my own did_* flags, clearing
autocmds, verbose mode, etc. etc.
Any help will be appreciated
Commands in filetype.vim are meant as part of the filetype detection
mechanism. They are invoked at BufNewFile (when creating a new file) and
at BufRead aka BufReadPost (after opening a new editfile and displaying
it in a buffer).
They should set the filetype of recognised files by either using the
setf[iletype] command (set the filetype if it hasn't yet been set) or
(locally) setting the 'filetype' option (set the filetype unconditionally).
Syntax coloring is done by syntax scripts, run once for each file at the
Syntax event, and should not need to be done repeatedly for files
already loaded. Similarly, setting options and declaring mappings for a
given filetype should be done buffer-locally in a filetype-plugin, which
is run once at the Filetype event, and uses commands like :setlocal and
:map <buffer>. These also, don't need to be repeated every time you
enter into the file.
You seem to be asking why the coloring isn't reapplied when you move
back to an existing window, I'd rather ask why it goes away when you
move out of it.
Best regards,
Tony.
