that hack didn't improve things for me either. but my problems were basically already fixed. ZERO redraws with ADW. ONLY redraws on LP with keyboard position change while in program and taking it out of a dock. in both cases, keep in memory, portrait only, and compcache enabled.
You can read about compcache in these threads, what it does, and why some people like it and others prefer not to use it.
