If you invoke SAS with the SYSIN system option or by specifying the name
of a file on the SAS command (ie. SAS FILENAME) and display a new
fullscreen window such as the FSEDIT or FSVIEW window or a SAS/AF FRAME
entry, the new window might not be full size. If you then display a
second new fullscreen window, the second window should be full size.

To circumvent this problem, invoke SAS using an autoexec file instead of
the SYSIN system option or as SAS FILENAME.  

For example:

    C:\Program Files\SAS\SAS 9.1\sas.exe -autoexec C:\myauto.sas

To ensure that the SAS open full size, you can also specify the AWSDEF 
option and add that onto the SAS.EXE command string.  The syntax for this 
option is:

   -awsdef 0 0 100 100
