Hi Jerry. Ubuntu 11.04, LyX 2.0.0, a 108K word doc, mostly text, gkrellm to measure CPU. By continually dragging the vertical scrollbar up and down very rapidly (twice to three times per second) I was able to get up to 80% CPU on one core and 70% on the other. Within 1 second of stopping dragging, the CPUs went back to their quiescent state, which was about 15% to 25%.
