hi Vincent, Win32 has a 2GB limit on virtual adress space for any single process. Microsoft decided for some reason to half down the available 4GB adress space in 32 Bit.
There's some obscure workaround to up this limit to ~3GB, but it is only working on some of the MS operationg systems. See the discussion on http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx Better way now is to use a 64 Bit environment and a 64 bit build. regards Ralph Vincent Bourdier schrieb: > Update : this sound like a memory problem : when my MV is around 2.0Go, > the application crash.
