IE6 to IE7 or IE8 compatability issues

Hi,

Now we r working on portal(EP 7.0) with IE6, working fine for All SSO and non-SSO , according to user request we r planned to change IE7 or IE8. I tested with IE7 and IE8 I found some problem's like below

1)  when the user clicking one iview(non-sso) its asking user id  and password even user mapping is fine.

     But same iview(non-sso)  is working fine in IE6( its not asking userid and password)

2) I have taken another dealer and tested its working fine (Point 1) but when I delete the cookies, files its asking the user name and

     password

  Now what i need to do for resolving the problem.

Thanks in advance !
