Hi,

Adding two lines to SetMarkupText("some XAML") methode solves the problem:


void CMarkupStatic::SetMarkupText(LPCSTR lpszMarkup)
{
    MARKUP_RELEASE(m_pUIElement);
    MARKUP_RELEASE(m_pMouseOver);
    m_pActiveElement = NULL;

    m_pUIElement = Parse(lpszMarkup);

    if (m_hWnd) 
        Invalidate(FALSE);
}

I use CMarkupStatic for displaying infotext for some records...
When I move through the records by keypress I update the CMarkupStatic by SetMarkupText("some XAML") for every record.

Problem: If I move the mouse across the CMarkupStatic window - while scolling though the records - the application crashes at the function:

CXTPMarkupObject* CXTPMarkupObject::GetValue(CXTPMarkupDependencyProperty* pProperty)

were the passed pProperty is invalid.

Callstack:

If I exclude CMarkupStatic::OnWndMsg() no crashes (but also no handling of hyperlinks,...)

I also tried the MarkUpSample. I added a OnTimer function to update the text of the CMarkupStatic periodically every 200ms. Everthing is fine except when I move the mouse across the control. After some moves the hyperlink does not show the mouseover and when exiting the program it asserts.

tx for help,
Bernt
