Sandbox prompt each time opening the same file on network share

Hi,

AVAST Internet Security each time asks if I want to open a specific file on a network share although “remember my answer” is checked.

Why? The application is trustworthy.

Thanks, Helmut

What is the name of the file with extension? Can you locate it within the autosandbox exclusion list?
If you move the file to your local drive then run it, will the file run normally outside the sandbox?
