[Pacemaker] Linux Cluster Management Console 1.1.0 crm configure show problem

I am not sure if this is the right forum or not however I will give it a 
go.  If this isn't the right place, please point me in the right direction

I am trying to use the Linux Cluster Management Console version 1.1.0 on 
a couple of VMWare Virtual machines running Fedora 16.  When I did the 
Fedora installation I did a "minimal" install and added in a couple of 
extra packages ncurses etc.

I have going at the moment a 2 node ( called c1 and c2 in /etc/hosts ) 
active/passive cluster setup.  The cluster is setup on pacemaker and 
corosync.  I been playing with the LCMC tool and I must say that it is 
an excellent product.

However, at the moment I am struggling with the crm configure show 
functionality in the LCMC.  To reproduce I click on a node, say my c1 
node, and then click on the right hand side crm configure show.  I see 
in the black console area that the command is executed.   However, since 
the configuration is quite large it looks like the less command ( or 
some kind of pager ) is blocking the flow of all the configuration 
information.  This results in a timeout (you have to wait quite a bit) 
in the LCMC and it generates the java stack trace at the bottom of this 
email.  It is an ugly stack trace to be sure...

My question is how can I overcome this issue so a crm configure show 
will work through the LCMC tool?

If configuration files are required for troubleshooting please let me 
know which ones and I will gladly provide them.  I am running the LCMC 
on the following JVM.  ( Note: I also tried running the LCMC on the Sun 
JDK in windows with the same results )

java version "1.6.0_22"
OpenJDK Runtime Environment (IcedTea6 1.10.4) (fedora-
OpenJDK 64-Bit Server VM (build 20.0-b11, mixed mode)

If it matters, I am logging in with the LCMC as a normal user and using 
sudo access.

Thank you for any help that can be provided.
