Hi Boris,

This is a bad interaction with another feature of TTree::Draw, which can use the content of a source file as the selection. Currently this feature does not require the file to have an extension ....

Subject: [ROOT] strange bug ?

Hello All,

I just found strange thing in both Root 4.04/02 and 5.13/01 Do the next things:

$ root -l



everything is working ...
Now try the next things:

$ touch e
$ root -l


Error in <TTreePlayer::DrawSelect>: Drawing using a C++ file currently requires that both the expression and the selection are files

        "e" is not a file
.! rm e
t->Draw("e","e>10"); OK !

Do you know what is going on ?

Thank you,
