Kepler

When I try to call "View Documentation" (right mouse click on a component->"View Documetation") and there is already a help window open from another comonent, than Kepler popup an error window and throw a exeption:

[null] ptolemy.kernel.util.NameDuplicationException: Attempt to insert object named "DocEffigy" into container named ".configuration.directory.effigy3", which already contains an object with that name.
