2.30:
 * Fixed: "Block:ptr is null" error when cutting attachments under certain circumstances.
 * Changed: It's easier to enter your shareware key now. No more "invalid key"
            if you entered a valid key slightly wrong.
 * Added: "About" button.

2.20:
 * Fixed: Non-mailbox .dbx files were being listed as extractable mailboxes.
 * Fixed: The correct mailbox filename was not showing if the mailbox was corrupt or not a mailbox.
 * Fixed: Attachments without extensions that have the same name as another attachment will now save
          and no longer fail with the mysterious "Block::ptr is null" error.

2.10:
 * Added: You can now extract Outlook Express AND Windows Mail mailboxes from the same interface under
          both Windows XP And Windows Vista.
 * Added: Duplicate file detection. It won't extract the same file twice.

 * Added: Support for Windows Mail under Windows Vista!
