Yeah, I've tripped over this MSVC bug as well. 'using namespace' in namespace scope 'leaks' out into file scope. It's pretty annoying because it still occurs over header file boundaries. The bug is still present in VC9, I believe, but I haven't tried 10 yet. (Microsoft knows it exists but declines to fix it in old compilers.) -- Trends on the internet are larger than they appear. http://surreal.istic.org/ Why did you resign?
