[ROOT] warning: file has the same version....

Hi,
I have a problem with an warning message...
I must confess I ignored it until I needed to Write new histograms...
The message is:

WARNING, class:TLeaf StreamerInfo read from file:r97.root
        has the same version:2 than the active class
        but a different checksum.
You should update the version to ClassDef(TLeaf,3).
        Do not try to write objects with the current class definition,
        the files will not be readable.

How do I "update the version to ClassDef(TLeaf,3)" ?
Do I need to get rid of the streamer or something like that ?

The r97.root has been obtained by h2root a r97.rz file 
and I am calling it this way:
TFile *r97 = new TFile("r97.root") ;

Any Idea ?

Cheers..
