Text values for Amount and Size of
falloff correction do not update when you move the sliders
5.0 all Editions
You can manually adjust the correction for brightness falloff (vignetting)
using sliders and text fields on the Overlap region dialog box.
Entering a number into the Amount or Size text field causes the slider to
jump to the corresponding position. Moving the slider should cause
update the text field appropriately. However, the text field remains
unchanged. Although the displayed value doesn't update, moving the
slider DOES update the value stored in the project file.
