AS iYahooCheck

Developed for the Adobe Air platform, AS iYahooCheck is a simple-to-use program that checks the availability of Yahoo! Messenger users. It can be seamlessly handled, regardless of your level of experience.
After a quick setup procedure, you can check out a slightly unusual interface consisted of a stylish, semi-transparent window and an uncomplicated layout.
So, all you have to do is write the user name of a Yahoo! Messenger buddy and click a button or press the Enter key to check his or her status.
AS iYahooCheck immediately displays the status on the screen, along with your friend's avatar image. In addition, you can save the respective picture to the hard drive with the JPEG format, once you specify the output folder.
The compact application runs on a low-to-moderate amount of CPU and system memory, so it should not put a strain on the computer's CPU and memory levels. It has a good response time and works well, without hanging, crashing or displaying error dialogs; we haven't encountered any problems throughout our testing. All in all, AS iYahooCheck is a pretty straightforward application when it comes to finding out a friend's status on Yahoo! Messenger.
