Just wanted to forward this problem report on to the list, in case anyone
knows more about this.  (Maybe this is already a known problem, I'm not

By the way, Dandelion looks like a great tool for outputting Smalltalk
classes/methods source code, if nothing else.  (I haven't tried the
analysis stuff yet.)

I also heard this problem from Ohshima - Squeak/Zaurus author.
It seems to be a problem of Squeak2.4 on Mac.
According to Ohshima, Squeak 2.4 on Mac sometimes fails to create an
instance of FileStream.
It silently returns nil, instead of a FileStream. Maybe the failure
occurs in VM.
(I cannot check by myself, because I'm not a Mac user).

I'll put this information on my web site. Thanks!
