IE 6.0 security

After installing of Internet Explorer 6.0 I see two security
problems:

1) After pressing of download link IE6 starts downloading
immidiately to some temporary directory (I even don't know
what directory) and after downloading is completed runs the file.
Is there a way to get Save dialog and not to run downloaded
file, as it was done in IE5?

2) When I Sign-in to some WEB site (for example, Hotmail), I fill
my e-mail address and my password appears automatically
in Password edit box. In IE5 I need to type password each time
I make login. How can I prevent showing the password?
