Screen Hunter is a program I use to capture images from the yellowfin program. It is just a screen capture program. I have everything set the way you told me to. The images are compressed because I had to shink them down to upload them here.
Do you have an image editor like Adobe Photoshop Elements or something similar?
You can export images right from YellowFin by going to the File Menu and then Save Screen or Save Selected. You can click the arrow / mouse cursor icon on the left and it will draw a selection box. Then go to File->Save Selected.
