There are a few issues in the Color Stretch dialog box:

1. When the asinh or gamma algorithm is selected, the asinh parameters and gamma parameters are always reset to the default. The user-entered values can not be kept and used.
2. When there are two or more images, when the lower/upper range in one of the image is set, the lower/upper range in all the rest images are set to the same lower/upper range.
3. The rangeValues are always reset each time when the Color Stretch dialog is open.
