Michael,

Each field individually controls how many decimal places shown so there is no global way to kick that up. If you download the SDK though, there is a tool in there called McSketch. This tool will let you edit the UI and do things like change the number of decimal places shown by editing the DTA files. However, you could also make your install of Carrara inoperable and have to reinstall so use with caution.
