<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">We have an MFC application which contains a vtk-window (vtk 6.1). The application runs fine in different versions (32-/64-bit) on Windows 7, 8 and 10. However, there is an access violation with Windows 10 using a 64-bit
Unicode build when the tab, in which the window is situated, is activated.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">This is the code from vtkWin32OpenGLRenderWindow::SetSize(int x, int y) that we manage to debug into before the access violation occurs somewhere in the system-dlls:<o:p></o:p></span></p>
