Thank you for your interest... Its the 1st time I meet this kind of problem. My Visual Studio is pretty old v2008 and the project settings are similar. Both Debug and Release share the same *.rc file.
They are both an MFC Static, not using ATL and Character Set are "not set".
My nonlatin character set is Greek. I can see the Greek titles in my dialog boxes in the editor. The only problem here is the Release version of the app. Don't know where to look for a problem.
