>drop a textbox on the form (must be first to get focus or set the tabindex to be before the grid)
>drop a grid on the form (such as dropping table on the form)
>add a when() code in the first column's object (textbox,...) for example, wait window ""

>run the form, the textbox will get focus
>click in the grid, any column other than the first column, the one with the When() code and see if the when will fires. It will happens the first time only. Repeated click will not show this behavior.
