can't add or organize URLs to my non-admin rights accounts

I'm using Windows XP Pro with IE 6.0 SP2. I have one Administrator account
and three general accounts without admin rights.

I'm unable to add and organize favorites on my non-admin rights accounts,
but I am able to add and organize favorites while logged onto my
administrator account. When logged onto non-admin rights accounts, I select
"Add to Favorites" from the Favorites drop down menu and nothing happens.
Similar to the "Organize Favorites" option, no dialog box appears. I'm
assuming the problem is associated with admin settings for the other users,
but I can't find any problems. However, when I'm logged onto the admin
account, I can add and organize URL addresses to my Favorites list.

Not sure if this is the cause, but I noticed the problem shortly after I
installed the Beta version of Microsoft Spyware.
