4.1i Project Navigator - Updating a project from 3.x to 4.1i results in unwanted cores being added to the project.
Keywords: update, core, project, XCO
General Description: When I update a project from 3.x to 4.x, any CORE Generator cores that are present in the project directory will be converted and added to the 4.x project, even if they weren't part of the 3.x project. (They will appear in the same level of hierarchy as the top-level source in the "Sources in Project" window.)
To remove unwanted cores from the 4.x project, right-click on the .xco in the source window and select "Remove".
NOTE: Any time the "Regenerate All Cores" process is run, all cores in the project directory will be added back to the project and will again need to be manually removed.
