Very interesting find, and I can confirm the same thing happens in
IE6.

I can reproduce it by placing the cursor at the beginning of a
password typed-in like "1234 56789 0ABCDE FGHIJK" and then use
CTRL+RIGHTARROW to move through the asterisks just as if the spaces
were there. (CTRL+RIGHTARROW in some applications like IE will move
you to the next 'word' in a textbox.)

This can come in handy when I typo part of a password and don't want
to retype it all, but this does have some slight security
implications.

Just something I've noticed on IE 4 & 5.5

If you enter a password that contains a mix of non-alphabetic and
alphabetic
characters to an MS IE password input and then use the keyboard to
select it
while holding down tab the cursor / selected region jumps between
the
non-alphabetic characters in exactly the same manner as it does when
you
apply the same technique in word, Interdev, vb etc.

It doesn't reveal the password, but it would seem to reveal at least
some of
the structure.

Eg

1 2 3 4 5
