Might I make a suggestion?
When clicking in the 'Search' box, the contents are deleted.
I find this to be unhelpful when refining a search, which is not an uncommon activity!
EG, I might search for "scanf matching newline"
But, I might not get any results (or too many!). So, the obvious thing to do is to refine my search terms - <click> - Oh nuts, I now have to retype "scanf newline"..!
While we're at it, I can't simply search again from the search results page, either. I have to use the browser's Back command.
These gripes aside, the forums are fantastic sources of help and I have found the answers to many puzzles here
