But if I don't have version 4 and don't want to download and install it, surely there must be a simple way to get the default graphics file onto my machine for 5.3.2 to use?
Part of the issue is that there is no 'default graphics file' for version 5, just an empty graphics palette. And the Graphics Palette(populated or empty) is, as I understand it, incorporated into the program prefs. Another issue is that the graphics can behave oddly on a Mac with an Intel processor. It helps to do the following in that case:
1. Quit Now Up-to-Date and open your Applications folder.
2. Do a 'Get Info'(Cmd+I) on the Now Up-to-Date application file.
3. In the info window, check the box beside 'Open Using Rosetta' and close the window.
4. Open Now Up-to-Date, and test the result.
