Looking for someone to help confirm this is a bug. In 7.1 you cannot create 2 different modules from the same desktop module folder using the option to create module from control.
Go to Host > Extentions and click the Create New Module button
If there is already a module that uses a control in that folder, you get an error: The module from the selected location exists and registered as 'Module Name'.
This is a new feature of 7.1?
