Hi, Brandos I ewould appreciate you probide Sbj line with your messages.
I used to delete right away any message with no "Subj"

It is not correct. MS has introduced this function recently,
Very likely they had had the same reason ROOT team had:
1. There is no standard for strdup
2. the behaviour of str<bla> functions provided with zero pointer is not defined
and causes the program crash (not under Windows only. It is still true for other
(UNIX) platforms also.
However I have to mention MS defines his StrDup function with
"#include <shlwapi.h>"
If one could avoid this include one may have avoided the name clash.
