Mulberry crashes deleting accounts

I recently changed jobs, and any time I try to delete the IMAP accounts for 
my old position (I ended up with two due to an acquisition), Mulberry 
crashes.  For now, I've set the hosts for each account to be "localhost" so 
it stops attempting to connect to the old servers.

This is windows, running 4.0.9.a1

Any thoughts on how to get rid of them would be much appreciated.  I was 
able to delete the identities, SMTP, etc, related to the accounts.  Just 
not the IMAP accounts themselves. :/

Thanks,
Quanah
