My appologies for not getting this summary out earlier, I was out of the
office for awhile...
The list of people who responded is fairly long and rather than takiing up
bandwidth listing everyone, I will just thank you all in one fell swoop
and hope that you all will realize how much I appreciate the help even if
I haven't thanked you personally.
The original question (paraphrased): Why doesn't Answerbook work with
eXceed and is there a work around?
The answer(s):
Answerbook requires a PostScript viewer to function and normally uses
(under 4.1.x) the NeWs software to display the pages. eXceed does not
have PostScript capability built in.
As for workarounds. Although, just about everyone agreed on the cause, the
solutions ranged from "It will not work with eXceed" to simply "Install
Ghostscript." What appears to be the ultimate solution to the problem was sent
to me by several people in the form of "a shar file for the docviewer mods
to allow reading Answer Book on non-DPS capable systems using ghostview."
This was apparently posted to the list back in April by Chris Philips (why
is it that you can never remember these things when you need them?? ). You
will also have to install ghostscript for it to work.
I have included the file after my signature. I will admit to not having
tried it out yet but everyone who sent it to me said it solved the problem.
Hope this helps.
