I should be more specific. The 2nd last button on my routine in filling a form is to "tab" to a "yes/no" button concurring if the record is correct or not. If it is a "no", the record may be wrong, but the information entered is what was reported to me on "hard copy", so I must enter it the way it's reported. Go back to the record bearer and get him to correct. It also helps confirm my typing. So it's confirming the correctness of the record so I can query the table for erroneous data.
However when I tab to that control the screen indication is so minuscule that your not sure if it's in focus. Secondly I want to ensure that the typist confirms that control are either "Yes/No", because the next tab in "New Record".
So to my way of thinking to change a thick border from Green to Red would definitely be "eye catching". thanks
