I have recently upgraded from AutoCAD 2008 to 2001. Now when opening a file from windows explorer (desktop vs the AutoCAD browser) and AutoCAD is not running. AutoCAD will startup and open a new drawing as well as bring up the dialog box for finding a file to open, which I cancel, THEN open the drawing that I have selected. I have not seen this before and am wondering what variable or option is causing to happen. I am also seeing two icons for the same drawing file in the Windows task bar.
