Enclosed below is a promised list of bugs/missing features.
o graphics editor doesn't work on IRIX 5.3 - I believe this is a known
problem.
o on AIX 4.1 it works just fine, however:
- on B&W screen one can't see button titles until he clicks on button.
Looks like both foreground and background colors are translated into
white on B&W screen.
I tried to change several gStyle attributes but it didn't help.
The same effect takes place in many places, for example when
DrawClass command is issued with <mouse-right-button> on canvas
o graphics editor doesn't have Line button. It draws PolyLine.
however, the corresponding macro (saved using "File" menu on canvas)
can't be executed afterwards: root complains:
root [1] .x emoe.C
Error: Can't call TGraph::TGraph() in current scope FILE:emoe.C LINE:11
*** Interpreter error recovered ***
Here is a macro corresponding to a simple polyline drawn with graphics editor
which leads to the diagnostics above.

o one can't kill graphics editor window otherwise then by stopping the
corresponding process or using the window manages tools, however
one can start many editor windows.
