I think I found the problem on the internet.
1. Vista still sucks
2. The problem is caused by an incompatibility between IE and Norton
security products. I use
Norton 360 (which came preinstalled with Vista) and have managed to correct
the problem of being locked out of most web sites by turning the transaction
security off on 360. Norton 360 can't tell the difference between good sites
and bad ones.
