Okay, I've tried it with Edge and IE and it works. Click page 2, wait while it pauses and fetches the search, then a "loading" message comes up and then it displays page 2 results.
The other search (Advanced Search) you're seeing is the old search the site had before we added the Threadloom search plugin. Threadloom tends to give more relavant search results, the company was started by former Google search engineers. TDR was in on their beta stages, and its been at release stage for a while. The catch is... since the search is remotely done instead of on TDR's servers, you get that pause between pages.
Oh... my responses have been and will be delayed for at least a couple of more days. I'm recovering from a bad case of bronchitus, on lots of meds and so I'm only getting in a couple of hours of work in each day.
