Hi,

I have a problem accessing two different cycles of a TREE in a TFile. I open a root file (there are some warning due to the fact that class used to write the file is not known to root, but this is not a problem) Access a cycle of a tree and then access another cycle, it seems then that I loose access to first cycle.

isdcsf3:0053 495> root
