Re: [gentoo-user] Double nautilus windows for each USB flash drive plugged in

Sorry, Alan.

The comments before yours were bottom-posted.

I'm afraid under these circumstances I can't find your top-posted  
comments pertinent.

I simply can't make any sense of them.

Your mailer also used HTML.

If you wish to make postings of this kind then I would be grateful if  
you could place me on your ignore list, and not make such replies to  
my messages.
