Re: [ROOT] "Error SelectPalette for Pixmap-0"

Hello
I suppose this happens within the ROOT-based stand-alone application
with the custom main()  entry point.

This indicates some the synch problem within built-in internal threads of
the
Windows version.

  I am not sure if it is possible to eliminate completely since the "core"
ROOT is
  not thread-safe yet.

 How ever the harm can be significantly reduced by replacing the custom main
with
 the custom DLL +  the standard ROOT main subroutine + gSystem->Load method.

I think Qt-based version will be more robust (and slightly slower) due the
internal lock
mechanism of the   Qt GUI code.
(see: http://www.usatlas.bnl.gov/~fine/QtRootDownload.html )

Best regards
                   Valeri

  Hello rooters,
  What about the problem "Error SelectPalette for Pixmap-0" I see that other
rooters, like Marcos [Marcos.Gimenez@ific.uv.es] are also facing it.
