ddd 3.3 - source sometimes not appearing

[Zdenek Sekera]

ddd 3.3 on IRIX with dbx, SHELL=/sbin/ksh

I have observed this:

Sometimes (probably 1 of 2) tries when I bring ddd up, open the
program, the source doesn't appear in the source window.
I just discovered when I do 'restart' at that time, ddd restarts
and the source appears. I can't figure out a pattern to that
source not-appearing after the 'open the program', though I have
a feeling it's somehow related to playing with preferences. It
often happens after I have changed and saved the preferences
(I am playing with dbx preferences) but I am not really sure
if that's related.
