Amongst my worst DP9 problems, is this issue I've been observing for weeks. Now, I'm pretty confident there's definitely something wrong with Autosave.
1.- It is the cause of a lot of my crashes, especially when I use VE Pro, and when I use MachFive (hosted within VE Pro and as a regular VI instrument as well).
I've tested this by killing autosave temporarily, and things get a little better. But just a little. Crashes will happen eventually anyway.
These crashes coincide with the moment DP autosaves, and worst of all, when it crashes when autosaving, it will CORRUPT THE AUTOSAVED file beyond recovery. Not even the Load command will be able to recover it. When trying, I always get an OS error indicating some kind of "End of File Error".
2.- The timestamps of the Autosaved files I see in the Finder DO NOT match my autosave settings in DP9's preferences.
I have it set to autosave every 6 minutes and to keep the latest 10 copies. In the Finder, I see time gaps of 20, 30 and even 50 minutes between the 10 most-recently autosaved files.
WHY????
Because of issue #1, of DP corrupting the last autosaved copy, and mysteriously NOT having more recent copies (as set by me in the preferences), I already lost more than 3 intense hours of work. Now I'll have to retrace my steps.
This is EXTREMELY WORRISOME.
I accept my responsibility for not manually saving enough. But then, I would do it every minute if I KNEW I could not trust autosave for sure. So, I say, MOTU fixes it ASAP, or they should take out that feature immediately, since it's worse to advertise something that doesn't work as if it worked! It creates a false sense of security

I LOVE LOVE LOVE DP. But it's been a naughty boy lately, and it's seriously starting to annoy me due to all the wasted time with crashes and troubleshooting.
MOTU, what would have to happen for you to understand that you need to dedicate most of your resources, at least for a full cycle, to IRON OUT ALL THE BUGS! No more features! No more plug-ins until everything just works. Please!

Oh, and did I mention that, since I updated to DP9's latest build, I NEVER get MOTU crash reports anymore. It just disappears without an explanation or anything. So now MOTU won't even know of these constant crashes!
