I'm running into a problem with a pop up that's generated via a form target attribute that gets set to "_blank" by page javascript when the form submit button is clicked. Selenium can't seem to intercept this window, and in fact the window opens up outside the Selenium window instead of appearing within the frame. I've tried various ways of grabbing the "_blank" window suggested by other users but with no success. So I'm wondering if there could be a way to simply run a search and replace on the javascript before the page loads. I want to replace every "_blank" with a "_self".
