Are you compiling the latest source? Also, are you using scons or visual studio? (or something else). It shouldn't compile as a beta unless you specifically tell it to ... I think.

The project file is mine, as far as I remember it doesn't compile a beta ... but maybe it does? I can't check right now since i'm not on windows. You should be able to find a setting for preprocessor and add STABLE as a define, maybe that will work.

Edit: I just checked my project file, BETA is defined. But only when you compile in debug mode, so when you make a release (probably compiling statically) it won't be a beta. I'll fix it anyway.
