-----------------------

* Game starts at MovieInstAnimStop

* Now not clear...
        os_TextCompare  -> calls  VDataBase_IMoaMmXScript::Release
        and Release calls to destructor
VDataBase_IMoaMmXScript::~VDataBase_IMoaMmXScript

Destructor is called only when counter of refs to database become zero after
release.
Valentina try destroy database, try close it, do loop ForEachTable and it
seems come 
To some bad table ...

May be issue is in wrong counters for Vdatabase object...
And it comes when you have several references to the same database,
E.g. In several windows

But then not clear why crash is random.
