Re: [Brahms-dev-l] root issue

Hi Catilin (and others)

Your message prompted me to do a little test.
I removed the statement in the dst generation 
BdstGlobal::Class()->IgnoreTObjectStreamer();

and amassingly the error message you  indicat are still there (the BdstGlobal no dictionary available still
appears) but  the plotting is ok. I do not want to dig more into this, but apperently this works . If someone want 
to give a deeper explanation be my guest.
The file is marginaly bigger (1%%).
