[GTALUG] odd error when running the screen program?

Hi folks, Both shellworld, and dreamhost, use Ubuntu as the basis for their shell workspaces. Sharing that up front, as this may be tied to Ubuntu. There is a program called screen, apparently common across some Linux distributions. one can create the equal of a screen shot, screen www.website.com followed by control a -h. This creates a file called hardcopy, with numbers going up for each file. However, when I run screen www.site.com Regardless of the site I get. screen cannot accept www.site.com no such file or directory screen is terminating. Suggesting that there must be a configuration issue since Debian users I know <and who have likely built there own stuff> are not encountering the same problem. Any tips? Kare
