Re: not a TStreamerInfo object

Hi Philippe,

I think you are right... Probably my situation was exactly as you described. (Unfortunately, I don't have any possibility to check it now, because now I am using the same ROOT version on both my working computers. However, I am in doubt that on one of them ROOT 5.27 or later have ever been installed...)

Best regards,
Oleksandr.
