same thing.
Then I found this in our script:
     gp.terminal = 'x11 1'
Smells like Unix to me ... well, commenting it out didn't help ...

Now I stepped through gnuplot.rb with the debugger, and the pipes are 
open before a command is issued:
@from_cmd => #<IO:0x2af0da8>
@to_cmd => #<IO:0x2af0cb8>

but still ...
C:\Program Files\ruby\tkgnuplot\rb9F.tmp:104:in `write': Invalid 
argument (Errno::EINVAL)
	from C:\Program Files\ruby\tkgnuplot\rb9F.tmp:104:in `_send_cmd'
....


Cheers, Ralf.
