Descriptive Problem Summary:
Using Dream Maker's icon tools, editing the green channel of a grayscale color fails when no other channels are edited.

Numbered Steps to Reproduce Problem:
1. Edit an icon.
2. Double click a grayscale color to edit it. Either the white or black in the palette will do if you don't want to add any medium grays.
3. In the popup window, edit JUST the green channel.
4. Hit OK.

Expected Results:
The green channel of the color will change.

Actual Results:
The color remains the same.

Does the problem occur:
Every time? Yes.
In other games? Every project.
On other computers? I only have one.

When does the problem NOT occur?
Green channel edits appear to work when the color is not gray. Red and blue channel edits appear to work either way.

Workarounds:
Edit the red or blue channel along with the green channel. Hit OK. Then edit to put the red or blue channel back.
