When I open windows' control panel, click the search bar and start typing, it always lose focus after typing in one character. If I click it again to regain focus, the problem wouldn't happen again. I'm wondering if this is a feature or a bug? As far as I can tell it happens in windows 7 and 8.
When you type the first character in the control panel's search bar then it shows the result of the programs that started with that character and move the focus to that list. You can call it feature but if you don't get the name in that list and you have to type the full name in search bar to get the specific program.
