The program does not connect to the internet. Instead, it checks your Desktop email program's inbox at set intervals, then displays a balloon tooltip above the Notification Area if you have new mail. The program opens a persistent visual notification of new mail. If you did not hear the "New Mail" system sound, or have that setting turned-off, you can glance at your computer from across the room and know instantly whether you have new email, or not. Most of us use the Windows screen saver. This program will not prevent your screen saver from turning on if you have no new mail. Your screen saver will be turned off when you receive new mail, so that the notification balloon can be seen. Unread mail will prevent the screen saver from turning on. No "Windows Installer" is included or needed. The program is not added to your Start Menu and no changes are made to your Registry. The program is a stand-alone executable (.exe) file.
