Thanks. I wouldn't have gotten very far without knowing the basic  
emacs keystroke conventions, and definitely not this far. :) I just  
didn't know that `pp-eval-expression' was bound to a particular  
keystroke.

Another keystroke I didn't know. This is what I get in the *Help*  
buffer:

set-mode-style-after-make-frame is a Lisp function in `aquamacs- 
styles.el'.
(set-mode-style-after-make-frame frame)

Not documented.


So obviously Aquamacs-specific code.

I activated up the debugger, then opened a new file and the debugger  
didn't start, probably meaning that `fit-frame' never got called. I  
double-checked and `after-make-frame-functions' indeed had the value  
(fit-frame). I suppose this means that the problem is Aquamacs  
ignoring this call...?

You seem to be right there.

Is there any way I can debug the hook itself, and maybe see why it  
doesn't call `fit-frame'?

It doesn't seem to get called.

That must've been my fault -- I expressed myself poorly (sorry, I'm  
not a native English speaker). When I call `fit-frame' manually, the  
frame is correctly resized to smaller if the lines are shorter than  
the current edge (within minimum limits), and bigger if the lines are  
soft-wrapped (also within maximum limits). I don't think that the  
problem is anywhere inside `fit-frame'.

That makes perfect sense and thank you again for your help so far.  
However, let me ask again, perhaps I might debug the hook itself and  
see what it's calling and what it's not? Is there a way to do this?

Thanks,
