Hi, when did you last update vm. There was an important fix in last couple days.

Thanks for post

Thanks for the update.

I have been trying to replicate and also to guess what the problem might be.

I suspect it is a notification about a usb or net port being shutdown by power management. It's the only thing that could be happening during unattended operation.

Having said that you can disconnect and reconnect usb cables without an issue so it's not entirely clear at the moment.

If you have any info about "special software" you have insalled, or hardware and power management info etc that might help. What about hardware and usb drivers? What and which?

thanks

Ok the log will be useful if you find it thanks

For better or for worse VS runs extensions in its own process. So if visual micro doesn't prevent exceptions from bubbling up to visual studio it can crash.

Generally Visual micro is well protected but an area that is new that differs from the older add-in code is managing tool windows which is where I might be looking. Did you have serial or debug running when you left your machine?
