On my Vista Ultimate machine I have strange problem with links in Outlook 2007 emails. If I click on the link I get the message "This operation has been cancelled due to restrictions in effect on this computer. Please contact your system administrator." I had been experimenting with Google Chrome and Apples Safari browsers, but I went into Programs>Default Programs>Set your default programs to make sure that Internet Explorer was back to my default. I cannot figure out what I am doing wrong. Any ideas?
