When I save and reopen a project its UML diagrams are empty.

[Juan Carlos Herrera]

I´m using Delphi 2006 Enterprise in Borland Developer Studio and I´m
experiencing troubles when I save a proyect with includes UML diagrams.

I open a new Delphi application for Win32, go to the Model View and start
designing UML diagrams (use case, class, activity, etc.), when I finish with
the diagrams I save all the proyect (File/Save All) and close Borland
Developer Studio. When I reopen the proyect all the UML diagrams are totally
empty, even if I click in the diagram´s 'Overview' button nothing shows.
This behavior is random, sometimes I save the proyect and when I reopen it
the diagrams are ok, but the second or third time I save and reopen the
proyect the content of UML diagrams is gone. I ´ve tried working with a UML
2.0 Design Project instead of a Delphi application for Win32 and the
behavior is the same.

When I save all the proyect, ¿Aren´t the diagrams supposed to be saved along
with the proyect? or ¿The procedure to save the diagrams is different?.
¿Have anyone heard about a trouble like this before?

I´m running Borland Developer Studio in a PC with Windows XP Pro SP2,
Pentium IV 3 GHz, 512 MB RAM and 80 GB HD. In
Tools/Options/Together/General is enabled the option 'Automatically enable
Together support for new and opened prohects'.

Thanks.
