If you're using Vista then you'll need to disable User Account Control only during the install of the Logbook Pro Palm Companion software to your PC. This is our only installer that is not yet UAC friendly. To disable User Account Control go to the Windows Control Panel User Accounts area, disable User Account Control, reboot, then install the Logbook Pro Palm Companion to your PC, HotSync to install to your PDA, HotSync again to initialize the data. You can now re-enable UAC as this only affects the installer.
Yes, custom columns are available on the PDA. When they are defined in the Options...Custom area of Logbook Pro PC Edition they will be available from the drop down navigator to the custom column areas on the top right of the Logbook Pro Palm Companion screen.
