Hi,
I had the same problem and fixed it by enabeling to items in the display settings:
Under Displays -> Display settings -> (choose profile and edit) -> Advanced
Enable the following to items:
- Keep current layout informed
- Have custom layouts expired?
They are the two items under enable shell command’s.
In the 1.8… version the second items was enabled by default, so I did not say it till today.
It works here so I guess it’ll work with you too.
