Good Evening! I'm trying to install Lysistrata in VirtualBox OSE. I can run it just fine as the"demo" user, but when I click on"install", and try to enter the password, which I assume is"demo", the window disappears. Any ideas? Thanks in advance!

You need to be root to install. When asked for a password for installing type"root"(no quotes).

Of course. If only you could see the colour of my face! Bright red! Thanks!
