I tried it and it solves the problem So here it is:
Attachments from Hotmail will not download unless the "Do not remember my e-mail address for future sign-in. (Select this when using a public computer.)" checkbox is unchecked when logging into Hotmail.
If that box is checked, the following message appears when trying to download an attachment:
"Internet Explorer cannot download...Internet Explorer was not able to open this internet site. The requested site was either unavailable or cannot be found. Please try again later."
This is only WinXP (SP1 or SP2) and IE 6 and Hotmail. Win2k works. Firefox
works. IE works with anything but Hotmail.
I must admit I would never thought of this by myself. Seems incredible that Microsoft=Internet Explorer=Hotmail has not yet fixed this.
