LaserSoft Imaging

Selecting 'BW film' in 'NegFix' and clicking on a frame to select or preview enlarged I have the 'Selective Color To Gray' dialogue box appearing. I click to deactive ( I do not need to choose selective colors to gray as I am already in gray scale). However, every time I select the frame or others the dialogue box is activated again.
The settings are Transparency/Negative/16 Bit HDR/
NegFix (for example) Ilford / Pan-f / Plus 50 6-6

The seemingly automatic appearance of the dialogue box interrupts my work flow as I need to constantly deativate or scroll in seeting to view other settings and select/view frames. Also the dialogue box is unnecessary in Gray Scale. How do I prevent it activating constantly ?

The SC2G tool is a necessary tool for greyscale scanning.
The Scanner always delivers RGB data which has to be converted to greyscale.
This requires a weighting of the color channel.
For most images this can simply be left as it is.
