Hi all:
I have a confuse problem. When I use a button in AMS5.0, then to click this button. It will change colors. If I specify the color changes from yellow to black. Then I want the black color to be fixed. It means after clicking this button, it will keep black color. It won't yellow color. How can I do? Who can give me a simply examples in AMS5.0? Thank you for advance.
