Thanks, I hadn't tried that exact strategy yet, duh...  However, nothing that 
looks applicable seems to appear.

Little gotcha's like that need to be pointed out in the README's that go with 
these programs.  It would have saved me a week.

In fairness, the error message did say that occasionally.

This program contains some python scripts, NUT-Monitor for instance, and 
while it only reports the online/offline, charge, load and remaining time, it 
also needs a considerable amount of typing into its gui to get access to the 
data.  I now have that setup as a Desktop button.

AI just now found that executing upsstats..cgi from a shell is very noisy, 
but the data from the ups does seem to be in this noise.  But I've no clue 
how to get firefox to run it instead of downloading it.

Yes it does.  Thanks.
