Larger Caption Buttons

I have failing eyesight, and would really like to have larger caption buttons in the tab bar.

I use large fonts and 125% DPI to read the text etc. and on some pages I have to zoom the page or the text, but none of these things seem to change the size of the buttons

Firefox bars and buttons change with the Windows settings, but CD does not seem to do this.

Is there any way I can increase the size of the buttons in Dragon ??.

Is this possible? If not I will move it to the Wish board.
