Nothing is displayed in the worldRaster, no matter what 
order I have the 'agentDisplay' and 'plotDisplay'.

Once bitten twice shy as they say. I had some problems 
installing last time. Due to outdated info which was very 
misleading and inappropriate, I'm on my own apart from this 
list. 
Also as a student I have restrictions on what I can do. For 
instance I tried to install the binary version of swarm-1.3 
for windows 95. On installing cyg_win the installation 
process attempts to make an icon in the programs folder. I 
don't have permission to write there so inevitably it 
aborts...
Similar problems with unix. I only have write permission 
for my home account. Therefore I have to be careful to 
change the 'normal places' where any swarm or associated 
software looks for things. 
For solaris I have to install the source version of 
swarm-1.3 and ALL the needed software. 
Plus time is short, I have to have this completed soon. 
At times like these the CD-rom version which is intended to 
be hassle free, seems like paradise :-)

This I have done and it fixes the output to the terminal 
window. Thanks !!! The problem with worldRaster remains...

I was curious as to why it stops if I have 
all -setStateStopped calls commented out.
