Well, I just instrumented the mouse motion event handler, and it is re-displaying the whole view at 200 frames/sec. So obviously, thats not what is causing the sluggishness. My guess is that the X-display is actually getting updated only about 5 (certainly less than 10) times a second. -- Neal Holtz http://www.docuweb.ca/~nholtz Dept. of Civil and Environmental Engineering, Carleton University, Ottawa, Ontario, Canada K1S 5B6. nh...@do...
