For the past 3 weeks I have been blocked from getting access to the Orbitz.com site on my laptop. I can access Orbitz on 2 desktops networked in my home, but not my laptop, which is what I take on the road. When I type Orbitz.com into my browser window (either IE or Firefox) the windows closes. It also closes if I do a Yahoo or Google search for Orbitz. I've scanned for viruses and spyware, but nothing is detected. I've turned off my firewall (Zone Alarm) and still can't access Orbitz. This started 3 weeks ago when I was comparison shopping for a hotel room. I had several browser windows open and when I went to switch to Orbitz from another site, I could no longer get into Orbitz. When I type Orbitz into the browser window it appears to start to load, then the window closes. Anyone else experiencing this or know how to solve the problem? Thanks.
