<p class="MsoNormal">The short version is that the MSVC compiler will do the wrong then when making a member function pointer to a class that it only has a forward declaration for. This can be fixed by either providing the definition for the class or by using
the /vmg compiler flag.<o:p></o:p></p>

<p class="MsoNormal">I did not experience this problem with Apples WinCairo sample, but I suspect it could happen.<o:p></o:p></p>
