Primary Context Checkbox in Person Contact form

Hello,
Just checking if anyone can tell me if the Primary Context in the Person/Contact entry form is not greyed out for anyone.
Here is a screen snippet.

If anyone can let me know it would be appreciated.

And believe it or not there is actually a criteria to select this on the Person/Contact Search on the Helpdesk form, but it is not greyed out, I am certainly confused here.

Got to love the copy and paste for screen shots in the forum by the way. :grin:

Bump??? Does anyone use Person Contacts?

Cheers
