Problem with the character set

So this is small code snipet that creates standard window with header control,
you will notice that program is processing WM_NOTIFY message and that is checking for HDN_BEGINTRACK notification message,( int3 at that point ).
All this is working fine and as expected but only when assembled as ANSI set,
( notice win32ax.inc ).
Including 'win32wx.inc' for the UNICODE support program still work but header control does not print item string as it should and int3 is never reached...
If anyone could clarify this mistery for me I would be really appreciated...
thx
