In src/generic/laywin.cpp (from wxWindows), the LayoutMDIFrame() function, calls the following code: wxWindow* clientWindow = frame->GetClientWindow(); rect = event.GetRect(); clientWindow->SetSize(rect.x, rect.y, rect.width, rect.height); Basically, frame->GetClientWindow() returns NULL, causing SetSize (which is a macro) to cause a segfault in DoSetSize(clientWindow, etc.). The variable 'frame' is passed to LayoutMDIFrame by our code: LayoutMDIFrame(this). frame->GetClientWindow() is indeed null as frame->m_clientWindow = 0x0. I am looking for a solution to the problem, but I wanted to send it to the list in case someone could fix it faster than I could. ahp ---------------------------(end of broadcast)--------------------------- TIP 6: Have you searched our list archives? http://archives.postgresql.org
