I got an email with this question:
(When he goes to his) "Hilton Hotels reservations account and I am trying to view an efolio of my past stays there is a hot link for each past stay. I click, the statement pops up for maybe a second and then closes down not minimized, gone. Does not happen in chrome so must be an IE issue. "
I told him to check the Privacy and Security settings, or try adding it to Trusted Zone (it is https). I haven't used IE7, so I am not real familiar with it.
Any other ideas?
