Netbooks often need a different interface configuration from laptops/desktops. If it's a network installation with people accessing Kar2ouche through a shortcut then they will (probably) all be using the configuration file. If you have a few netbooks then one solution is to locally install. That way they use the configuration best for them.
The interface config file is in kar2ouche\content modules\default\interface\interface.ini. Change
interface.dat=1
smallface.dat=1
to
interface.dat=0
smallface.dat=1
on the netbooks. If you have problems contact us through the support address on the web site.
