10.6.8, 2.1svn Scrolling User's Guide takes 13 seconds. No misplaced cursor. This scroll rate is between what I measured for 2.0.0 and 2.0.2 using the special preference file line. Subjectively, for me, the somewhat slower difference for 2.1svn puts the experience back into "painful" regime, but it is still better than 2.0.2 without the special preference file line. Jerry
