[Inkscape-user] Screen, icons and themes

Hi, all.

I was playing around with 'inkscapec.exe' because now I can see several output message that I had not idea. One of those is the following:

(inkscape.exe:3660): Gtk-WARNING **: Could not find the icon 'object-visible'. The 'hicolor' theme was not found either, perhaps you need to install it. You can get a copy from: http://icon-theme.freedesktop.org/releases

I know nothing about GTK but, since I am a Windows developer I became curious of how can I change some elements of the Inkscape interface without recompile the software. I did a little search in the Inkscape.org WEB site but I didn't find anything.

Someone could point me to a reference place?

Thanks a lot, Alessandro Antonello
