With this very small utility you can kill you freezed programs with one click. For example you double-click on it's icon, the target-like cursor show-up, then on the next program you click, it's terminated. We've took the idea from UNIX world, where people use Xkill. Basically, this utility is a windows clone of Xkill.
Editor's review of One Click App Killer

This tiny app quickly closes frozen programs, but clicking too fast or in the wrong spot could cause problems. One Click App Killer doesn't have a standard interface, as it simply turns your mouse pointer into a bull's-eye. Click anywhere on the frozen application's interface to quickly eliminate it from your screen and memory.

We found it is possible to click too fast and eliminate the wrong program. Also, clicking outside the frozen program's interface could close Windows. Those were rare problems with this stable utility.

Other than user error we found nothing wrong with this application. It performs as promised and with low overhead. We only wish it was a simple executable without need for installation. Any level user will be happy with this freeware's performance.
