I'd just like to share my experience updating my wife's pmail from 4.41. Things did not go well.
Post upgrade:
after the logo screen we'd get a cryptic sql failure message from spamholder about a corrupt database
then we'd get the 'what's new' screen, and after that a message that there were autosaved messages that hadn't been sent (there were none)
I then (and this was the purpose of the upgrade) I changed her pop server from my box (running mercury) to pop.gmail.com:995
-upon restart, the new pop profile had reverted to the old one. The new one was there, but invisible, I had to manually add back on each restart and disable the old one. Even after deleting, the old profile did not stay deleted.
-the spamholder error persisted, as did the 'what's new' message, as did the 'autosaved messages' message.
-there was no menu item for the spamholder in the tools menu (!)
Trying to force a preference write with ctrl-exit did not help, the problems persisted. The pop profile kept reverting, the 'what's new' message
kept popping up and the spamholder spat the dummy every time. Nor could I turn it off, sans menu command.
Hijinks, hair pulling and blue language ensued. I won't trail through all the unsuccessful attempts at solution here, which I sifted from the help file and
searches of this forum.
In the end, I tried renaming pmail.ini. Upon restart, the program requested I enter a new email address, new pop server (hey, it did NOT give me the
option at that point to enter a secure connection, and of course the pickup subsequently failed - it might be a good idea to allow for that in future!)
Problems solved. No more spamholder errors, the spamholder item on the tool menu is now present, no more 'what's new' pop-up spam. No more mention
of auto-saved messages. Go figure.
There were no permission problems with the old .ini file, that was the first thing I checked.... the program just would not write to it, and the missing menu
item has me completely baffled. (Before anyone asks: win xp home on that machine, no UAC a la' Vista or Win7 running interference here)
Conversely, the upgrade to 4.62 from 4.5x on my own box went without a hitch.
-P.
