Thanks for the tip. It solved the problem for the C examples, but after closing the window, when I try to do another plot, my lisp complains about access violation, and will afterwards die. It seems the most reliable interactive driver so far is wingcc, that seems to works well if I close the window using the mouse. Closing it with the keyboard (was it space? or maybe RET or ESC) won't close the window, that will stay there frozen. Control is anyway returned to the lisp repl, but after some plots, I get memory corruption/access violation errors and my lisp dies on me. It doesn't seem to happen when I close the window with the mouse.
