But that information alone probably doesn't help you. You could share the entire screen I guess, instead of just a single application. Maybe creating a virtual desktop and associating gretl with that desktop could make that easier. (From what I read Apple calls that feature "Spaces".) As a more radical solution, you could also run a virtual machine and that way all gretl windows stay in the window of that machine, which you could then share. At the latest gretl conference there were some discussions about a single-window layout, but other new features had higher priority AFAIK. cheers sven
