link_to issues with I.E.

It sounds to me like you are re-using
the window object. Try opening the popup with a unique window name, possibly
derived from the object id.

For example:

link_to "Open Show", { :action => "view" }, :popup => [, 'height=300,width=600']



Make sure the window name is _blank

                    <%= link_to(,
                      { :controller => 'foo_controller',
                        :action => 'foo_details',
                        :id => foo
                      }, :popup => ['_blank', 'width=720, height=250'])

There an alternative that worked for me:
