RoboCopy XP026 Return Code

With RoboCopy version XP026 the Return Code is always 0 (even with a fatal
error) instead of what it should be according to the documentation. Is
anyone know a workaround to this problem or if there is an update that fix
it?

I was also wondering why the version XP026 is 3 times bigger than XP010 for
the only few extra features, was there major flaws to address in version
XP010? Is there any features and flaws comparaison table of the different
versions?

Thanks!
