Chris, this is fantastic! Despite years of LC/Rev scripting, I had never heard 
of either of the properties you mention, and now I've read a bit more about 
them I really don't understand them much - presumably there must be a payoff 
between using "static" and "dynamic" layerModes, or the engine would just opt 
for "dynamic" all the time. Anyway changing these (at run time - they 
apparently can't be stored as states within one's stack file) has made a lot of 
difference to the snappiness of my app. I have a lot of images which the user 
or the program can move - some are families of images representing different 
states of an object. There are probably about 100 all told, although only about 
10 are visible at any one time.

Anyway I set the acceleratedRendering and the layerMode of all the moving bits, 
and things look a great deal better.

As a slight excuse, I find that these properties are described but not fully 
explained in the LC Dictionary and are not mentioned at all in the User Guide 
or the IOS Deployment Notes, so it is not that surprising that I have never 
come across them.

Thanks again

Graham
