Hello All,

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

$ root -l

t->Draw("e");
t->Draw("e","10<e");
t->Draw("e","e>10");

.q

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

$ touch e
$ root -l

t->Draw("e");
t->Draw("e","10<e");
t->Draw("e","e>10");

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,
