Well, this is really strange, I even start to believe my Peg is bewitched

This is my Problem:
After the Simple Mail vs Yam I thought I `d like to give Simple Mail a try. No Problem so far, started it, then it moaned about wrong nlist.mcc
Version (20.115 is needed) I checked in mossys:classes/mui (which should be loaded before anything else afaiu) the nlist.mcc there was according version FILE nlist.mcc: 20.115

And now it get strange:
If I do version nlist.mcc (which should display the loaded nlist) it says 20.111 ????
Ridiculous eh?
I did search on my entire Harddisk, and deleted every other found nlist.mcc but the problem is still there ?!
Is there a way to find out from which place a library is loaded? Scout also just shows me what library is opened, but not from where it is opened. It is totally mad.

You had this issue too?? I went through this a year and a half ago,
with the nlist.mcc and YAM v2.x. I very thoroughly documented my
trevails in emails to the core gods but didn't get far. THey kinda
said I was crazy, so I thought I was. Long story short, I am running
YAM 1.3.5 and it works fine, but its kinda primitive. I use it as the
'backup' email in case my Mac has a problem-which it does occasionally
when one of my Clinton-era hard drives decides to go tits-up

I miss the Clinton Era

Anyhow, I was never able to solve this problem, I did all the same
things you did. The version checker that you use when checking an
icon's version as from Ambient, seems at times different than the
shell 'version' command-it is possible for two different numbers from
the same file it seems. I guess they'll fix this bug too when they
can.

You can use snoopdos or snoopium to know where the library is loaded
from.

Henes: Well I did this first of course ;)
But it didn`t show the path?! (Perhaps because the lib was allready loaded) Anyway I tried snoopdos again, including it during startup and that gave me the hint: There was a nlist.mcc.elf in sys:classes/libs/mui which i have completly overseen, this one was older.
But out of curiousity, is this a bug or a feature?! I thought that Mossys: has allways priority over the stuff located in Sys: even if it is named .elf ?

I had the same issue. I ended up having to rename all the nlist.mcc on my drive and replace it with the new version. Though in the 1.4.5 release I have the proper ones not in mossys: so I removed all from sys: and it seems to have solved all my issues.

You know, I haven't tried it again with MOS 1.4.5. Maybe I should.
Will YAM display html in emails? It seems many emails nowadays have
it, needless to say they look horrible in old school YAM 1.3.5

I notice you included snoopDOS in startup, I shoulda thought of that
Back in the day, some Amiga mag had an article about running such
a utility early in startup to catch bad things happening-I followed
the article's advice and got a much more stable Amiga as a result but
that was back in the 3.1 days. Good times..
