Installed siag, Mowitz, XawM, neXtaw and font* packages from gslapt. Executed above mentioned commands. I am still having some problems with pw.
I can select fonts from drop-down, but only "New York", "Times" and "Times New Roman" show a change. All others revert to "Times" when I go to type. Also, selecting a different font size, or bold, or italic, only seems to affect character spacing.
