Hello,

Ah ah ! Something has changed since this morning.
Here are the messages I see in the bash console when I start scilab 
(these messages where not here this morning):

Could not enable OpenGL pipeline for default config on screen 0
Set the EventHandler status  of figure 0 to false
Exception in thread "main" java.lang.NullPointerException
        at 
org.scilab.modules.gui.bridge.CallScilabBridge.setEventHandlerEnabled(Unknown 
Source)
Set the EventHandler of figure 0 to
Exception in thread "main" java.lang.NullPointerException

Source)
Set the EventHandler status  of figure 0 to false
Set the EventHandler of figure 0 to
Set the EventHandler status  of figure 0 to false


Now, When  do a plot(X,Y), here is the window I see (without any 
infinite loop) (see included image).
All the points of the curve are here ... but in disorder :-)
