Thanks for the report - I found that problem in unit WPXMLFile. Please modify the code after line 450 (insert begin,end):
Code
else if p^ > #32 then
begin //V4.20a
FWroteElement := TRUE;
if (p^ >= #32) or (p^ = #9) then //V4.11f
begin
s := s + p^;
end
else if p^ = #10 then
s := s + '<br/>';
end; //V4.20a
