Michael, out of the blue Moi 3.0 has started crashing.
I'm running Windows 10 64 bit and have 8GB of RAM.
My graphics card is AMD Radeon HD 7800 series
I've made no hardware change for many months.
The crashing has been going on for a while - a couple of weeks. It was occurring before Windows 10 Anniversary update and following the update.
I've kept an eye on CPU usage and Memory usage and noticed nothing unusual. Neither show any peaks at crash time.
When a crash occurs it is restricted to that instance of Moi. Any other Moi instance seems unaffected.
When the crash occurs there is a Windows notification but no Moi notification.
The Moi 3.0 program folder does NOT contain any crash reports.

I have tried uninstalling and re-installing Moi 3.0 though perhaps an especially thorough uninstall is required?

I'm limping along doing very frequent incremental saves.
Time between crashes is 10 to 30 minutes approximately.
Program instance does not crash if there is no activity in that instance.

Hope this is any easy fix...

Mike.
