Linker errors in release mode

Hi, when compiling an application in Release mode I get the following errors:

afxcw.lib(afxmem.obj) : error LNK2005: "void __cdecl operator delete(void *)" (??3@YAXPAX@Z) already defined in libcp.lib(delop.obj)
nafxcw.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __endthreadex
nafxcw.lib(thrdcore.obj) : error LNK2001: unresolved external symbol __beginthreadex
Release/HProgram.exe : fatal error LNK1120: 2 unresolved externals
Error executing link.exe.

I have no idea what they mean or how to deal with them, in Debug mode there are no errors.

Thanks for any help,
Jason.

Check your project settings under 'C++|Code generation'. That should read "Multithreaded DLL"
