Create a class, right click on it, choose Create Parent / Package. Click Undo twice (the first undo seems to restore the package size), the package gets deleted together with the class. This is unexpected, the proper undo behavior would be to extract the class back from the package and delete just the package. Click Redo, the package appears again on the diagram, however the class does not (though it is re-created, as it can be seen in the Diagram Navigator).
The complete build ‘build_20060707’ is released. Please run the updater (inside $vp-suite-install-dir/bin) to advance from the hotfix release to this build.
