Thank you for your response. I have “hover” set and I am using the simple code in the header. The strange thing is that when I do one search I get the vertical result display. When I do a second search the results appear on a new page. Then any subsequent search displays the results on a new page as well.
The other issue is when I do the first search, the vertical results appear but it's beneath my navigation. Before the update of the search plugin this was working fine, now it's not. Do you know how I can remedy this?
