Thanks for looking into this and the feedback. Sorry for the omission regarding OS. I connected (using ssh -X) from a Mac (running Snow Leopard) to a Linux machine and ran ROOT remotely on the Linux host. The X you saw was probably because the window was a client of the X11 server application running on the Mac. I also tried this directly from the linux computer terminal (i.e. not remotely), and got the same result. So it doesn’t seem that the Mac is involved.
Is it possible that some visualization component is missing in my environment, e.g. libGraf3d.so? I’m saying that because linking C++ code with root libraries started to complain about missing libGraf3d.so after switching to 5.34:
[url]Missing libGraf3d.so
Update: I confirmed that root-graf3d has not been installed; could that explain the display problems?
Thanks,
Neil
