CheckBoxColumnProperty in inmethodgrid updates

[Chris Colman]

Has anyone used the new editable column classes in inmethod grid
provided by Tom Burton?
 
I really like the extra functionality Tom has added to inmethod grid but
I can't get the check box to appear as a check box.
 
It appears only as text showing either true or false.
 
Has anyone else tried these new classes and got them to work?
 
Regards,
Chris
