I have had this problem and added the following code to MainFrame.cpp and WinPos.h and WinPos.cpp to control where the app opens upon startup. DirOpus needs something similar.

void MainFrame::OnMove(int x, int y)
{CRect winRect; GetWindowRect(&winRect); winPos.set(winRect); CFrameWndEx::OnMove(x, y);}
void MainFrame::OnSize(UINT nType, int cx, int cy) {
CRect winRect;
CFrameWndEx::OnSize(nType, cx, cy);
if (!isInitialized) return;
GetWindowRect(&winRect); winPos.set(winRect);
}
