From what I see, the glutPassiveMotionFunc is not called if the state of one of the buttons is Down. Why is this? I am trying to draw the outline of a rectangle when making a Sweeping Selection in an RTS, and I can't do it because i Set mouse coords when the user left clicks(GLUT_LEFT_BUTTON, state=GLUT_DOWN)(and holds), and then I want to use glutPassiveMotionFunc to set other mouse coords. I draw the rectangle until the user lets go of the left button, GLUT_UP. But it won't work. Is there a work around? Or other way to get passive mouse coords? Jeff

bump, cuz I can't find any information on this.

glutMotionFunc() is used for when the mouse is moved and a mouse button is down.

Ha, works like a charm, thanks!
