Links open in two targets when field is configured with 'Open link in new window'

Hey. This is for 6.x-2.x (feb 25, 2011).

I see some new behavior that is troubling. Link fields that are configured to 'Open link in new window' will open a new window and a second later will also load the link url in the root window.

If I use 'Default', 'Open link in window root' configurations, it works as expected, as well as when I enter a url manually or using link_node and node reference. It only happens on links created with the Link CCK field. The weirdest thing is that if I read the link (made using CCK field type) with Firebug it only shows target="_blank", so I don't understand how this could happen unless there's a problem with the php.

• All the links listed under the field label 'Website(s):' are created using link cck field.
• Check the behavior of the other links in the node/page too, you'll see that all the non-CCK-Link links are are working properly:
  • location links are created using node reference
  • the links in the body of the node are made using link node
  • if you click the Link to our facebook page abover our sitewide like box
