Searchtempest is now working properly in Safari and Chrome browsers. The only minor annoyance is that an extra google search box is displayed with the results. The author let me know that for some reason, when you turn that off, it also causes the scroll bar to turn off for Safari. Likely something in Google's code, since the views causing the issues are actually code google returns back.

Nathan, the author, also let me know that the site is going to be completely refreshed with a new "awesome" design. It's a nice resource already and I'm also looking forward to them supporting Kijiji.
