Hi, Rooters: There is problem in "Int_t TChain::Add(const char *name, Int_t nentries)" for the latest root_v3.05.07. I use Mandrake 9.1, and compiled 3.05.07 from source (the one before "root_v3.05.07.source.tar.gz. . . Jul 25 21:44 9737k" worked fine, but not the lastest one). Attached please find three macros. "fillTree.C" to fill the tree and write to a root file. Then run "chainTest_1.C" and you get "Error in <TChain::LoadTree>: cannot find tree with name h in file aaa_0001.root". Interestingly, macro "chainTest_2.C" (which is the same as "chainTest_1.C" except that it calls "TChain::AddFile(..)") works. Yiqun Wang
