Hi Rooters,

I try to issue

	TMapFile *mfile = TMapFile::Create("histos.map","UPDATE"...

in compiled program and got a message:

Warning in <TMapFile::TMapFile>: map file already open in write mode,
opening in read-only mode.

and file really opened in read-only mode.

What might be a reason?

I run ROOT 2.23/12, Linux.
