If I search for something then click on the document on or near the found search term, it doesn't always focus the document and when I start typing it just goes into the search box.
I'm running build 2217 Mac OS 10.8.1.
In my experience, it never focuses on the document. I have to press escape to close the search box before making further edits in the doc.
Same build, OS as above.
