Installed the new V17 update (build 321) when prompted this morning. Great to see the long list of fixes. And (fingers crossed) it seems much more stable so far, especially with more than one project based on the same clips open. This is a big deal for me at least. Only one crash after 5 hrs use. I still have the 'auto save after every edit' option on, and it crashed doing a fast start/stop preview while it was still saving, which doesn't seem unreasonable. I just need to slow down a little! Thanks to all involved...
