Re: spawn broken on IDL 5.3 / solaris ?

Unix IDL 5.3 also has another problem:  idlde doesn't handle files greater
a few hundred lines in its editor.  More lines than that and they just don't
up on the screen. Tech support told me they switched to a 3rd party
chroma-color-enabled editor in 5.3.  They did not tell me when to expect
a fix.
