Hi Mads, many thanks for your advice! I had tried everything previously apart from ‘deleting the render files’ which I did first thing this morning. Now at the end of the day and no crashes all day!
I did notice that heaps of files I imported into a Footage bin at the beginning of the project had disappeared mysteriously. But the sequences are linking to the files brought in with xml sync files out of tentacle.
Anyhow, since it’s behaving now, I’m going to proceed cautiously but optimistically 🙂
thanks again, Helen
