The Save Button is Grayed Out
You can't save files because the "Save" button is grayed out on the FileCenter Save dialog.
The button remains grayed out until you have selected a valid destination for the file. This means selecting at least a drawer or folder. A cabinet alone isn't a valid destination.
Select a drawer or folder to save the file into. If you need to, add a drawer to your cabinet from the "Drawers" button.
