When choosing to create a new gadget, the 'Person' category is missing from the list of options.
This can be caused by 'Use Individuals' being set to 'No' in System Behaviour.
Resolution / Workaround:
A workaround is as follows:
Log into CRM as an Administrator and go to Administration –> System –> System Behaviour,
You should see a dropdown box for ‘Use Individuals’. Set this to 'Yes' and save.
Person will now appear in your Gadgets lists.
This is fixed in Sage CRM 7.2f
