We are aware of this problem. We warn our SGI users in the page
"Availability and Status".
We have only remote access to SGI machines running 5.3 and the problem
seems to be connected with the X server not the client library.
Apparently the problem disappears on IRIX6.2.

We will investigate the problem with B&W screens and menus.
When working on a B&W screen you should do:
gStyle->SetFillColor(0);

This problem was fixed in 1.01/02 on May 8.
The code generated in the invokation of TGraph contained a spurious
comma. If you remove the comma just before the close parenthesis,
your macro will work (2 places).

You are right. You kill teh graphics editor window using the standard
