When you click the customize button, you should then see an example format, with each element in a blue oval. Hover the mouse over the "7" oval (hours), then click the triangle that appears. In the popup list, select "00-23". Then place the cursor after the "PM" oval and delete it. Close the window, relaunch iCal. That is one hell of a non-intuitive interface. -- Scott
