How to modify default package configuration in APD

Hi,

I'm starting a new design in APD (i'm very new to it) and the new package configuration window shows up when I start a new design but it closes right away? not allowing me to select the type of design. In the manual it is said that you can change this:

Figure 2-30 shows the New Drawing Configuration dialog box that appears after you name your drawing and choose a drawing type. You choose the component configuration and accept the design parameter defaults in this dialog box. You can override these defaults. See Setting Drawing Parameters .

However I can't find any option that allows me to change the default package configuration (die top/bottom, wire bond vs flip chip, etc.). 

Does anyone know how to do this?

Thanks!
