Pop up window also opens same info in another full widow

When I create a pop up window, the same information will also appear in another full window. I want only the pop up window to appear, of course. I do the following: 1. select my text. 2. link it to the page I created that will have the content that I want to appear in the pop up window. 3. go to behavior. 4. Open in browser window. 4. select the page I created with the text that should appear in the pop up window. 5. set the dimensions, etc. for the pop up window. 6. close and save. I then open the main page in a browser (both Firefox and MSIE), click on the link Up pops the pop up window, but the full page is also displayed. This full page is just what I do not want. I have also tried different targets in the properties of the main page, but still get the same result. thank you in advance. Carl Jordan.
