Histogram bugs?

HI, I am running root 2.0 on linux. 

First, I would like the new look and feel of root 2.0.

But I have observed that GetIntegral() (and the functions required to get
it, like GetBinContent() ) don't work in the new version. 

eg:

0% root

CINT/ROOT C/C++ Interpreter version 5.13.42, Jan 23 1998
Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.
root [0] h=new TH1F("h","h",100,0,100)
(class TH1F*)0x0
root [1] h->Fill(10)
root [2] h->Fill(20)
root [3] h->Fill(30)
root [4] h->GetIntegral()

this just hangs right here, whereas is 1.03.09, i get

0% root

CINT/ROOT C/C++ Interpreter version 5.13.36, Nov 30 1997
Type ? for help. Commands must be C++ statements.
Enclose multiple statements between { }.
root [0] h=new TH1F("h","h",100,0,100)
(class TH1F*)0x0
root [1] h->Fill(10)
root [2] h->Fill(20)
root [3] h->Fill(30)
root [4] h->GetIntegral()
(Stat_t)3.000000000000e+00
root [5] 

as expected.

I also notice that when i try to look at a histogram in a .root file
that was created with v2.0 using v1.03/09, i get

root [3] SingleRecoils3.Draw()
Fatal in <operator new>: storage exhausted
aborting
Abort

Thanks in advance for any help.
