hmmm... on MSDN

I haven't found any info about a SYSTEMTIME structure filled with
zero's. In fact, it's true with all Windows version, but not under
Vista. MSDN talk about dwFlags only.
IMHO Borland IsBlankSysTime() is a useless function... with this patch
in CNNotify(), control seems to works correctly
else begin
if FShowCheckbox and (dwFlags = GDT_NONE) then {patch}
// if FShowCheckbox and IsBlankSysTime(st) then {original}
FChecked := False
else if dwFlags = GDT_VALID then
begin
ciao Paolo
