[horde] Internet Explorer V7 does not saves Username in login Form

[Josep Cols]

Hello:

I'm ussing Horde Groupware Webmail Edition  1.2.7  (horde  3.3.9)

With Internet Explorer V7, the system does not saves the username and I 
need to type it every time.

In IE configuration I enabled the Forms save and, also, the pòp-up 
windows, but this does not helps

Is it a way to save the Username and not need to retype it every time? 
Another bypass could be to put the username on the URL: is it possible?

Thanks
