Hi xerao,
Does this only affect the Classes view on the left, or do you get the same kind
of errors in the Properties view on the right?
Are you working on a project created in a previous/different version of TBC? Or
is this a fresh project but you imported existing RDF/OWL files into it?
If you select your project and do:
File > New > RDF File
and confirm the default settings, do you get the same errors in the new file?
