[Metakit] error while database is on windows file server

[Florent Lejeune]

Hi

We use Metakit to store miscellaneous information for our programe. It works on windows, 
macosx and linux.
It happens that when the database is created on the windows network, we have some problem 
with the windows application (we use metakit-2.4.9.6).

Below you will find a program that creates a file, adds rows, and retrieves information.

The Find function doesn't return anything and a manuel search also gives no result. In our 
main program, the Find() function remains in an infinite loop.
It works fine with other plateform combinations : from windows client to simple windows 
sharing, from macosx client to windows file server and from macosx client to macosx apple share 
file server.

Thanks for any suggestion about this.

PS: our windows file server is a macosx with Samba. we compile with visual studio 2005
