Re: TMap::Update()

Hi Boris,

  please follow the comments in SetMapAddress():

http://root.cern.ch/root/html/src/TMapFile.cxx.html#emEGw

Before doing the TMapFile::Create() make sure that all needed shared libraries are loaded (i.e. if you need graphics, first create some canvas, so the graphics libs are loaded, use gSystem->ListLibraries()).

Cheers, Fons.
