I'm setting up an Ubuntu 12.04 PC for my 71 year old dad. I'm trying to keep thing simple and BIG. I found a way to set most text, buttons and icons to large size, But there is 1 problem. The control box of a form (minimize,maximize,close buttons). I can seem to find a way to change their size. The window caption font size changes, but the control box stays the same. Anybody know if it's even possible to change that?
