Ya I caught that new feature.. very nice... as far as the crashing I am referring too.. it was occurring when switching fx... I actually got both snow leopard and loepard to do it but it took a very long time to happen in leopard whereas in snow leopard it happened sometimes within just a few changes. This happened when changing fx from the library window.. perhaps this is the cause? at any rate I will test 257 when I can. Thanks for your support of a great product.. now if only apple would support multiple video cards in a way that was conducive to what we are doin
