colorbar hidden, not deleted
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
show/hide icon shows/hides colorbar, but when hidden it is still there, invisible, but confusing the mouse and ocasionally blocking the navigation when dragging datasets onto the invisible colorbar. When the navigation is blocked, only restart will unblock it. See the thread:
"[Paraview] endUndoSet called without a beginUndoSet."
