Rules account get modified

[Guy]

Hello

I have a dozen email accounts setup in Outlook 2002, along
with a folder under Inbox for each account.

I also have a rule for each account and it reads like this:

Apply this rule after the message arrives
through the my_account account
move it to the my_folder folder

Well, several of my rules work perfectly. But for a few,
it seems like Outlook always resets the "my_account"
parameter to another account. I go back and change it
again, but as soon as I leave the screen and come back,
the account has been reset again.

Does anybody know what's wrong and if there is a fix for
this behavior?

Thanks
