The first field in the queue will be used to display the check box, which means displaying an icon. And any field that displays an icon needs to have a Long variable immediately following it.
A word on CML classes
I'm going to be releasing the classes from this article series as part of the The ClarionMag Library, so they all follow the CML compiling convention which by default expects to find the classes in CMagLib.DLL.

Next time: Making the Initialize call more flexible, and turning checkboxes on and off.
