Hi, MWSnap is a simple program to use for taking snapshots of what you are seeing on the cams.  You didn't say what it was you had a question about on how to use the program so  have you read the help instructions that is built into the program?  It does have many features that I don't even use so don't have to worry myself about lol. main things that I can remember I had to learn was to use the window/menu snapshots (control + shift + W is hotkey ), on the settings have it autosave to the folder I wanted it to autosave to in jpg format, and in the settings of windows media player I had to uncheck the use overlay option in its settings.  If you have any other specific questions feel free to ask us.
