After upgrade to CRM 2015 Spring Release 1 (version 7.1) Some Business Rules do not work when loading a form.
A Business Rule should ex. show some field if a certain values is set. This works fine before upgrade to Spring Release 1 (7.1)
After upgrade the Business Rule do not work when loading the form, only if the value is changed.
In order for this to work again this, you have to set a new setting in System Settings.
This setting will be removed in version 2016.
