I am using a Logitech Mouse which has a special switch near the mouse wheel. Using this switch, the mouse wheel can be de-clicked. With the clicking disabled, not only the mouse operation is much more silent, but I can also push the wheel and runs freely.
Used with fotoARRAY that means an enormous fun for me since the images scroll through so fast. Since I have several images taken in a series, the motives come to live, similar to a flip book. I know no other image browser which is so fast.
If you want to use this scrolling without having to turn the mouse wheel, you can also use the track box at the bottom of the fotoARRAY UI. It activates automatic forward or backward skipping in various speed. Click on an image to stop.
This is why we say "experience your images in a whole new way".
