yes, i have seen at least the save/asterisk problem before, using 8.01 on linux. it appears after copying and renaming strict type definitions and the VI that contains these controls using a console. after loading the VI, the save/asterisk problem appears. a workaround that works for me, is to open the renamed type definition, change e,g the label and save it. the VI can be saved without any problems.
hope, that helps.
