I bought a medical insurance policy from United Healthcare this year. When I login and go to the 'Help & Contact us' page, the middle frame (which has what I want, the top and bottom frames being boilerplate) it appears for a fraction of a second, then disappears. This happens even when I start in safe mode. I could use it at the library, which has Windoze computers. I just installed the latest Opera to read a message UHC had sent.
