[ROOT] TGraph plot cannot be generated.

After I upgraded ROOT to the newest version,
I came across two problems:

(1) I have an old root file with a tree 
    which gets updated every 15 min by 
    a compiled C++ code using old lib of root.
    
    After I re-made the root, 
    the old code is using the new lib to update
    the old root file.
    
    Is this the reason why the rootfile gets corrupted ?
    
(2) With the new version of ROOT, 
    my old script which plots a TGraph could not work 
    any more.  
    
    The message:
    Error in <RootX11ErrorHandler>: BadAccess (attempt to access private 
    resource denied) (XID: 0, XREQ: 88)
Error in <RootX11ErrorHandler>: BadAlloc (insufficient resources for operation) 
(XID: 0, XREQ: 84)
    
    Running Tetris gives the same message.
    
    guitest however is ok.
    
    What do I need to do to correct the problem ???
    
  thanks,
  HP
