Ok, I guess I'm not being clear, and will have to give up modifying my screens as now none of the screen programs work.
Do this, open the default 1024 set, click on some of the controls, you will see they are OEM controls, in fact, there are not STD
controls for some functions (I believe edit gcode is one of them). Now that you see that, create a brand new screen you don't
need a background, on that screen, add an image button and set it to an oem function like load gcode. Watch what it does.
Now create a normal button and assign it the same function, and watch what it does.
You will see the button works, but the image button does not.
As a former programmer, I'm just trying to let you know on the image button save, something is missing, a bit is not being
set if it's an OEM code.
I hope I am being clear as I'd like to continue to use your program, but can not until this feature works correctly.
