No… I tried that and it was ok…[/quote]
There might be some subtle difference between your development toolchain and ours. What VS version (inc service pack level) and Windows SDK do you use on your Win7 development machine?
Did you try building Bram’s test program on Win7 with VS2010 (without any changes to his Introjucer project) and running it on Win8? That would at least rule out any compiler/linker flags being the root of the problem.
