Comment 5 for bug 987507

I'm Inkscape 0.48.2 r9819, so same version, recently installed. I'm new to Inkscape so this could be a newbie thing and if so, would appreciate advise. I presume tooltips to be built in functionality. I however see no tooltips with mouse-over anything. Is this an Inkscape preference - I've looked and can't find. Or is it system related and set somewhere I can't find? Thanks.
