After searching the internet some more I found the same answer. Following is the code, in case anyone else has this issue. HWND hDlgWnd(NULL); HRESULT hr; IOleWindow *pOleWindow; //Sometimes the progress dialog sticks around after stopping it, //until the mouse pointer is moved over it or some other triggers. //This process finds the hwnd of the progress dialog and hides it //immediately. if (SUCCEEDED(m_pprogressdlg->QueryInterface(IID_IOleWindow, reinterpret_cast (&pOleWindow)))) { hr = pOleWindow->GetWindow(&hDlgWnd); if(FAILED(hr)) { hDlgWnd = NULL; } pOleWindow->Release(); } m_pprogressdlg->StopProgressDialog(); if (hDlgWnd) ::ShowWindow(hDlgWnd, SW_HIDE); m_pprogressdlg.Release();

Did you ever figure out the solution? I am having the exact same issue.
