It's getting a little old and rusty looking but it's still the best CHM reader on the Mac that I have tried.

Excellent, I have treid all the othet CHM viewers for OS X and this one is the only true Cocoa free app that allows me to search into a CHM file (also xChm does it, but it is a multiplatform app ported to OS X).

I can open Chamonix, but as soon as I try to open some CHM file, Chamonix silently crashes or closes. No error message is being displayed.

Console dispays this info:

2006-07-05 10:48:20.447 Chamonix[15172] *** -[NSCFArray addObject:]: attempt to insert nil
/Volumes/Users/Users/james/Documents/Code/Chamonix_11/chamonix/MyDocument.m:339: failed assertion `doc'

It looks like path is wrong... I'm not "james", and currently Chamonix is on my Desktop.
