[ROOT] Two problems

Hello,

I have two problems with root.

Problem 1:

I want to display an histogram with just its name in the stat box. According to
the manual, I should be able to do that with:

gStyle->SetOptStat(1);

but the stat box still displays, in addition to the name,  Entries, Mean and
RMS.
Note that this problem is specific to the value 1 as an argument (with 0, 10,
11, and so on, it works as expected).

Problem 2:

I want to use TPaveStats to chose the position of the stat box of an histogram,
ie:

h->Draw();
TPaveStats *st = (TPaveStats*)h->GetListOfFunctions()->FindObject("stats");
st->SetX1NDC(0.6) ; st->SetX2NDC(0.9) ; st->SetY1NDC(0.6) ; st->SetY2NDC(0.9);

At the command line, it works, but inside a macro, I get the following message:

Error: illegal pointer to class object st 0x0 219  FILE:detptstudy.C LINE:154
*** Interpreter error recovered ***

I'm using root 3.05/07 for gcc 2.95.2 on RedHat Linux 7.2.

Thanks for help.
