I have a problem in increasing font sizes for menus and palettes. I have found the way to do this via Preferences - the default font size is 10pt. I would like to increase to say 12pt, but when I do so the 'apply' button vanishes of the bottom of the screen. I move the window as far as possible to top of screen but 'Apply' remains invisible even when I temporarily make the tool bar disappear. Most windows of this type have a facility to be able to drag the window to make it smaller, but the preferences window does not have that ability. Any ideas please?
