Not entirely sure what has happened here..
I added a couple of topics by way of the ContentLayout tool window. I inadvertedly typo'd their names. I went to Visual Studio to rename them because I couldn't figure out how to rename them via the standalone GUI. I saved the project in
Visual Studio and came back to the stand alone GUI. I got the error message that the Project Explorer window was already initialized. Then the application crashed. Now the project explorer window only show very briefly when the application
is in the process of loading then vanishes. Trying the tool bar button or menu item makes no differance.
This is with the latest alpha release downloaded today.
