Thanks but you are misunderstanding my problem.
There ARE pictures to click.
I type the correct grid numbers in the input box to the left of the "just click" button you highlighted.
I then click the button you highlighted.
The auto mouse then clicks the correct grid numbers.
When the automouse clicks those boxes they first correctly receive a check mark
BUT then the selected box incorrectly fades away and loses the check mark.
AND the automosue doesn't do the final step - click the green verifiy button which is shown just above the "just click" button you highlighted.
