Just tried with the Visual C++ Toolkit 2003 which is available from MS
for free (They say it's the same compiler as in Visual Studio .NET). The problem stays the same. Any hints on this?

Maybe I need an SDK update? What did - no, superfluous question as you
use VS.NET ;-)
I'll do that next unless anyone has a hint on what else might be wrong.
