Any way to turn on all cockpit tooltips?

Hi, One noticeable difference between the 737NGX and the 747X/8 & MD-11 is that there were *many* more cockpit tooltips in the latter a/c. I do have the checkbox checked for cockpit tooltips. I use them a lot due to low vision. Is this a limitation of FSX, or were they just not included in the 737NGX? thanks,dan 'lensman' davison
