More bug fixing
This wasn't a problem when I was testing locally because I was the owner/administrator. Eventually figured out you can save it into the %appdata% folder, so I moved my ini files into this location. Hopefully this won't cause any problems for people with older OS's (eg XP, Vista etc.).
I also re-drew the inventory screen, looks much nicer now and fits in with the rest of the GUI.
Otherwise, feedback from the demo has been positive, thanks to everybody who has downloaded it and tried it!
