In GUI, I have basically made pushbuttons with a dimension of 10 rows by 10 columns. I am wanting to be able to use the 'Tab' button going from left to right and top to bottom. With the Tab Order Editor opened, the further I move one pushbuttom from the list (ie. the button on the 10th column in the 10th row, to the 2nd column in the 1st row), it'll takes about 20 minutes. By the time it finish processes, I would be able to make any save changes. Any thoughts or does GUI needs a update?
