One detail is still quite dangerous IMO: When you are on the setup window, with sites / user(per site) lists, and select a site, the buttons edit / delete and so on become active. If I click "Delete", Core FTP server doesn't give any kind of confirmation, just deletes the entire site with users... That can be dangerous and can possibly ruin entire workday
So please, can you make a delete confirmation dialog in the next version of Core FTP Server? I'd really sleep better after that 
And yes, I usually hate all kinds of "all you sure you want to blah blah" confirmations, but this is kind of "enough important place to have one".
BTW: Where is the tray icon of the core ftp server? Is it supposed to be shown? I guess I had that on regular Win XP PC, but now I should use this on Windows 2003 Server (as autostart as service enabled).
Thanks.
