Hi HP,

Concerning your first problem. With the new version one must be able
to update an old file. Could you send me:
  - a copy of your old root file
  - the script creating your new TGraph and storing it in the file

About the second problem, it is likely that you use an X11 emulator
or an old X11 server. Could you edit the file $ROOTSYS/system.rootrc
and replace the line:
X11.FindBestVisual:      yes
by
X11.FindBestVisual:      no
