I have been using Draftsight for about a year. No matter which version I use, Draftsight  always opens with a file named; "NONAME_0.dwg". This file is usually the last file I either viewed or worked with. I have searched through the help files and all of the option sections and find nothing so taht I can set Draftsight not to open the file it calls, "NONAME_0.dwg".

How do I alter the preferences, so that no file opens by default?
