In VTiger 7, there were couple of major changes made to how the related records created or opened. Quick create is one of those changes made. Once you are in a record and trying add a related record, it opens the Quick Create popup and not the full form. You have to click on the “Full Form” button in order to access it. Another would be the summary popup of related records. Once a related record is opened, instead of opening the full page, it gives a summary popup with key details on it. To open the full related record, you’d need to hit the “Details” button.
