Never mind... I finally rewrote it in MFC (VS 2005) and it's working like a charm...
I encountered other problems like with CListCtrl sorting: solved by rewriting my own function, borrowing also the function of someone else to display a little arrow (bitmap) on the Header line.
I also rewrote a CColorLabel Custom class derived from CStatic using part on the code of the CReadOnlyEdit which was based on CEdit...
The last remaining problem to solve is with HotKey/Shortcuts... But I can live with it as the most important ones are working fine anyway !
