I've added a sub-grid to the Account form for Addresses. I've confirmed that the Navigation area includes Addresses and I can add them that way, but I can't add by clicking the "+" on the top of the sub-grid; clicking it does nothing. Other sub-grids with plus signs work properly so I know it's not a popup blocker issue, and I have the system admin security role.
The only change that's been made was modifying the address view. Can changing that break the add functionality of a sub-grid? (I restored the view to it's original state but still no luck.)
