I noticed the search form results page address functionality doesn't work, ie it doesn't direct the browser to the results page set in the settings.
I had a look at the code with firebug and I see it does show the results page url in form action, but it shows id of current page in the hidden input value.
Changing that input value to page id of target page, or removing it altogether made it work as expected.
Hope you can fix it in the next version. Thanks!
