I have also noticed a slowness of screen redraws when typing or navigating on my 600Mhz iBook that was not noticeable with LyX 1.3.7 but is noticeable with LyX 1.4.4. Specifically when typing within figure floats and equations. My question is: Is there a way to speed this up? i.e., turning off instant preview, etc. or is it finally getting time to upgrade the old iBook. Thanks, Bob Lounsbury
