I did start the server in my .emacs as you noted below.

Hmmmmm. Thanx for this tip. When I run "C-h c M-." it returns
ESC . runs the command sn-find-tag
When I run it from the emacs session invoked from the command line
("normally") I get
ESC . runs the command find-tag

Bravo. 

So now I see what you mean. The binding is, as you say, overridden to
query S-N. Hmmm, what if I bind a key to this function call with 
(global-set-key  [f5] 'find-tag) 
...for example
I can issue the command with a newly bound key rather than the default
one which has been overridden. 

Hey it works!!

I don't know if this is a bug or not. From the cygnus help:

The Source-Navigator search function replaces the find-tag
command (Meta-period) when you search for a symbol. Because the
other tag commands are not yet available inside Source-Navigator,
you need to use the equivalent emacs commands, if available. 

So I can't tell if it's a bug. I'll email them about it anyway. 

I didn't realize the M-. was calling a different lisp function
altogether. 
Is the function "sn-find-tag" able to be aliased to "find-tag"? If so I
can probobly just alias  it if I can figure out how this is done...

What about item 1?

Any ideas here, or does this sound like a SN problem? I'll email Cygnus. 

Thanx again for the help Tom.
