What download of gnuplot 4.0 for windows did you use?  I used the 
gp400win32.zip which didn't have a bin directory.  I ran the same 
command through irb and it works like you said because its in 
interactive mode.  I also don't appear to have a window menu.  Is that 
in the graph window or the command line window?  Maybe the download 
wasn't good.  Anyway, I would like to run scripts through the command 
line and not enter it each time through irb.  That way, the persist flag 
becomes necessary but I can't get it to work.  Thanks for the help.
