I'm responding to my own message in order to provide some insight into how I solved the problem. I click on another object in order to lose the focus while the check buttons' value is 1. Then from that objects' click method I call the Toolbars' ButtonClick method passing a character value as a parameter, then trap for TYPE('BUTTON')<>"O" within the ButtonClick Method.
