I'm trying to reproduce but it's not popping for me.  What is the setup 
of your fs?  mkfs options, mount options etc.  And how are you running 
aim7?  I'm using reaim with the default reaim.config and workfile,disk, 
is this what you are using?  If not please attach your config and 
workfile so I can be sure to be doing the same thing as you.  Thanks,

Josef
