[V4MD] Closing database blues

Hello Ruslan,

my db is quite small. I have seven tables, most of them with 32 fields for
the whole db. There are less than 1000 records in the whole db and the sizes
are:
*.vdb	->	2.5 MB
*.ind	->	1.1 MB
*.blb ->	10.8 MB (approx. 100 pictures)

Not too much stuff at all.

I really think that I should rebuild this thing again (XML export &
re-import) because I had a lot of crashes during the development and I
changed things in the structure.
And for a NT system mine is rather old and already a bit wicked. I have to
check this on other machines, too.

Cheers
Olaf
