What are you using in the variants? I could see where some problems might occur if you are using safe arrays, but if you are just using the regular variant union variables, then I'm not too sure.. What are the memory leaks saying? Are the leaks explicitly of object of CYourClass? Or are they variant objects? //------------------------   CSignature::Jeff() ;   PostMessage(WM_QUIT) ; //------------------------
