hi, i''d like to draw a quad each at a random location of the screen each time i click the mouse. I already have all the mouse routines, but when i click and i manage to draw the quad, when i release the mouse button it disappears...

Is this a joke? If you are clearing the screen then the quads will disappear, magic.
