Hi,

I made this applet but it is not resizable.
if i put 100% in width and height in the HMTL tag of the applet when I resize the window frame of my browser the applet is resizing to fit space but the context of opengl does not fit the new dimensions.
and i would like for example that the spining square would be resized up on a window resized up.

thank you for your help

GL11.glOrtho(0, 640, 0, 480, 1, -1);
you're specifying 640x480 all the time...

elias added some resizing to our awt test recently:
