Hi again all,


I found something rather curious today. Last week I had ran my 
simulation through various stages taking snapshots for a report.
I came to look at the png's today and they're all blank black pictures?
So I re-read the GUI introduction to check if I needed to set something 
but it seemed to say just click the button - which is what I'd done.

Anyway I tried running again and this time it worked, which was strange.
I then tried again but this time I re-sized the display window (as I had 
done in the first set of snapshots) and the snapshot was again a blank 
black screen.

It's not too much of a problem I can just re-generate the pictures at 
default size. I don't know if you had come across this before so thought 
I'd let you know, seems like it'd be fairly easy to fix.

Thanks
