Thanks, Bonnie. This looks very simple. I should be able to put this in my subclassed business form, right?

>>A user noted that when a checkbox control has focus and a letter for one of the hot keys is pressed (e.g., D for the delete button), the hot key fires without requiring Alt+D to be pressed.
>>Now I realize that the user should not be pressing anything besides Enter or Space when on a checkbox control but . . .
>>Does anyone have any suggestions other than 1) setting the tabstop property to false; 2) eliminating the hot keys; 3) training the users?
