Please forgive me if this has been brought up in the past already (and I hope it isn't too trifling to bring up), but enabling the search distance check box under the "advanced search form" seems impossible to use when viewing on mobile browsers. The slider control just will not respond, and frequently, the browser will interpret the "sliding" as the user attempting to go back a page in the browser. Also, occasionally, it'll draw the distance radius around an arbitrary location; I'll attach screenshots to explain what I mean about the latter situation (I'm located on the East Coast, not the center of the United States), and again, in that situation, will not respond to user feedback. The slider just doesn't budge.
Sometimes, if I play with it carefully, I can get the slider to move, but only very slightly, and then the map goes blank and shows a "NaN" distance. I've tried this on multiple devices, and multiple browsers. I'll attach the browser/os information below (the former is for Safari, the latter is Chrome).
Thank you very much for you time
Max
