OK - I must be losing my mind! I did nothing - changed nothing --- all I have done is that bit you suggested to drop in a butterfly then switch it to a face......all my faces have begun working now! This makes no sense whatsoever!!!!!!!
I didn't re-render the sequence.
Ah...but....after Gil suggested I try the USBlyzer I had to restart the computer to finish that install --- and did not run anything with a face after that restart. So perhaps something was locked up in memory somewhere from one of the earlier crashes we were working on and that restart cleared it.
I don't know - but I'm completely surprised now!!!!!!!
And, Gil, my Monster Mash sequence played through to completion and didn't crash and the face sang along just fine! Now, granted it is still ever so slightly jerky - but tolerable. This is running from the exe you sent me this morning not from the one you had me modify on my own machine....so maybe commenting out those two lines like you had me do, might get rid of the rest of that slight flicker.
I notice the flicker especially in the marquee effect because it doesn't smoothly move around the edge - but hops skips and jumps around the edge. On the face, because most of it doesn't change, I don't see it as much - though he has a slight flicker.
