   Hello Karen

  OpenScientist / Lab can't produce hbook files. The hbook (or Zebra in fact) format
is supported in read only by the interactive applications as a conveniency to the past.

  By default the Geant4 TestEm* produce hbook files. I think that this default should be 
changed to be "xml", since all the three AIDA implementations around support
this format in write and read, but I am not the master of this TestEm code....

  Moreoever the TestEm code is in general not protected against a "return 0"
if the AIDA::ITreeFactory::createTree fails (then you had probably a crash here).

  Some of the TestEm (including TestEm3)  permits to change the file format through
a Geant4 command (then without recompiling). Then, if using OpenScientist change
to xml (or root format if there are some big tuples around).

  Anyway, the libLabZebra (or Zebra driver of Lab) is not reconstructed
by default in the OpenScientist distribs since it uses the old CERNLIB and f77. 
Then,even if trying to read hbook files for exa with OpenPAW, you will have the 
"DLL libLabZebra" message.

 To rebuild the lab Zebra driver on your distrib :
      OS> <be sure to havel old cernlibs around>
      OS> cd <OpenScientist install path>/Lab/<version>/cmt
      OS> <setup>    (csh> source setup.csh, sh> . ./, DOS> call setup.bat)
      OS> make Zebra      (DOS> nmake /f nmake Zebra)
It will build LabZebra DLL.
