Aftere much chasing in circles I eventually saw a hint which led me to
discover that the culprit was the anti-ransomware protection of my

'OFF' has solved the problem.

This ios only new behaviour and I am not aware of an Acronis update
which could have caused the problem. Presumably then it something that
Microsoft or Adobe have changed.

it's clearly an issue with acronis.
