Hi Bob,
1. I will remove the hard coded button widths, not sure how that got there. I noticed it too on this site.
2. I don't know what you mean, I see no interference on this site bewteen the search input and the site menu. I do notice that on FF on Linux the "enter search terms" is not completely visible, but on windows its fine.
The poll issue I think is only a problem after a fresh compile or after the application has just restarted. There is delay between clicking the radio button and seeing the result due to the JIT compiling happening on the ajax request. But after the first requests its fast and there is no delay.
Joe
