using Jetpack on my site (WP 3.5.1, Twentytwelve) causes this minor but nevertheless annoying issue:
When I'm logged in, every time a page with an entry field loads (search box, new post etc.), the focus on the default field (and the cursor) is lost after a second or so. This makes working on admin pages slow and annoying as I am forced to use the mouse to reactivate the standard field every time a page is loaded.
I assume this must be caused by some background loading process as the focus is lost exactly when the site stats chart icon shows up in the admin bar. Site stats itself is not the culprit, because this happens also with stats deactivated.
When I turn off the WordPress.com connection everything works fine. I encountered this behavior in Safari, Chrome and Firefox (newest versions).
Is there anything I can do about this?
