When I close the program (after i saved the project) and open it again later, then happens strange things with my UCD's

-sometimes actors are hidden, they are there again, if I restart the program.
-In all without one uc diagrams, the directional association marks were killed by the program. may be the saving function does not work correctly.

How to reproduce:
Make some folders in the use case view, may be 3 or 4. then put in every directory one ucd with more than one actor (not sure, but i believe its since then) make some directional associations with some use cases. save the project.
close the program
open it again
