I've been gaining more confidence in that approach, and when I think about why this may be more effective, it ties back to my first statement which is that areas of code that have needed multiple fixes are more fragile. With that potential in mind, a good test session in the area gives me more confidence than a one-off retest of a particular bug. I also think at some point, you have to consider the case closed -- meaning you have to begin looking elsewhere for bugs because by over-focusing in one area of an application, you could be missing defects in other areas of the application. I often remind myself to "keep hunting."
