I am developing SDI application in vs2k5. It has same designlike *SearchOptions* Sample program which comes with Toolkit but my SearchPanel make with few changes on requirement. My project contains movable splitter.On the left side, it has Panel which use Dialog to draw panel and on the rightside, it has List view and base class is CListView. My panel class *CMailPanel* contain CXTCaption object m_wndCaptionand I set Office2003 Theme on it and its work fine and no problem in Resizing. Iwrote some code for set Office2003 theme on List Header in *OnInitialUpdate*function in view class, m_header (CXTHeaderCtrl) is member of my view class,

HWND hWndHeader =GetListCtrl().GetDlgItem(0)->GetSafeHwnd();
m_header.SubclassWindow(hWndHeader);
m_header.SetTheme( xtThemeOffice2003 ); 

If I enable these lines of code for set Office2003 theme onlist view then my panel view act some abnormal behavior on resizing. Can youguide me, how I fix this bug?
