Text turns to mush

I am using this code to print color text to a rich edit box:

Code:

---

void CRichEditDlg::OnBnClickedButton1()
{
        // TODO: Add your control notification handler code here
        CHARFORMAT Cfm;

        m_Richer.GetSelectionCharFormat(Cfm);

        Cfm.cbSize = sizeof(CHARFORMAT);
        Cfm.dwMask = CFM_COLOR|CFM_BOLD;
        Cfm.dwEffects = CFE_BOLD;
        Cfm.crTextColor = RGB(0,0,255);

        m_Richer.SetSelectionCharFormat(Cfm);

        CString text = "Now is the time for all good men to come to the aid of the party";

  SETTEXTEX SetTextEx;
  SetTextEx.codepage = CP_ACP;
  SetTextEx.flags = ST_SELECTION;

  m_Richer.SetSel(-1,-1);
  m_Richer.SendMessage(EM_SETTEXTEX,(WPARAM)&SetTextEx, (LPARAM) (LPCTSTR)text);
}

Everything works well, the text prints to the box and the colors are correct, but when I scroll up or down using the thumb, all the text gets distorted. Any ideas?

Thanks

I think I have tracked this down to the WinXP bug that distorts text when smooth scrolling is enabled. So I tried to handle the Vertical Scroll for the rich text edit box.
Right click on the rich text edit, select Add Event Handler...Select my class and Message type as EN_VSCROLL select Add and Edit then add this code:

Code:

---

void CMyScanDlg::OnEnVscrollRicher()
{
        // TODO: Add your control notification handler code here
        Invalidate(); 
        UpdateWindow();
}

and.......... it doesn't work :(
The text still "melts" when you use the vertical scroll.
Any help appreciated.

Did you ever fix this? I'm trying to draw rectangles that seem to "melt" upon scrolling in either direction. Also, the rectangles are completely redrawn when I minimize then restore the window but apparently the origin moves.

My code to draw the rectangles is

CRect TempRect = pDoc->GetNode(i); // The points for the rectangle
OnPrepareDC(pDC);
pDC->DPtoLP(&TempRect);
pDC->Rectangle(TempRect);

I have tried a variety of fixes in OnPrepareDC included setting the mapping mode to MM_LOENGLISH and setting the origin at 0, 0 but nothing works.

Any help?
