When applying my style to any control, I can set the alpha value of the appearance to any value without any problems The problem I have is when doing that with the CheckEditor I use the alpha value to indicate that this field is not important When I do that, if the control is styled using my isl, I get an out of memory error I am enclosing a project that contains a button and a checkbox Under each of the controls, there is a slider that is hooked up to control the alpha value of the control Moving the slider that is hooked up to the button works fine When doing the same for the checkeditor, I get the out of memory error
