I have a similar problem with the very first window I plot. The graphic windows freezes after plotting any graphics, like
plot sin(x)
After showing the graphic, the graphic window doesn't update if you move another window in front of it. If you type a gnuplot command that doesn't use the graphic window, like a=2, it is ok. However, if you try to plot another graphic, the whole gnuplot freezes.
