I don't know if you got a satisfactory response to your message, but
I use XP and the following should work.

If it is the last price you want, cut and paste the text between the
"***" symbols into a file with a ".iqy" extension and it should work.
The actual data returned is determine by the "&f=l1" part of the URL.
If you want different data, you will need to replace the "l1" with
a different "Yahoo format code".  There is a list at the bottom of
this message.  You can combine more than one format code for example
"&f=l1p2" returns the last price and the % change separated by a comma.
You will then need to convert text to column's based on comma separation.

I am posting this here as others may find it useful
