Random Event Sounds resides in the sys tray and will randomize the sounds associated with common system events like close program, minimize, maximize, start windows, etc. as well as other programs like AOL, Quicken, Windows Explorer, Windows Messenger, etc. It will also randomize Windows Screensaver and Desktop Wallpaper files.
You can make a list of your favorite sounds for each event, and at given intervals the program will pick a new sound out of the list for each event. You can also cause the program to pick new sounds at any given time by right-clicking on the sys tray icon. Each event can individually be excluded from being randomized even if a list is provided.
You can also decide for each event if you want Random Event Sounds to randomly select a file, or cycle through the list you have provided.
Even if you do not want Random Event Sounds to pick files for you, you can disable the Auto-Randomize and manually tell it to randomize whenever you tell it to.
