Hey!
I just checked, and everything was working fine.
To complete the first location, you need to visit all the rooms in the house — only after that your objective will change to "Find grandpa's will."
Once you read the will, close it using LMB, next an event should trigger, after that your objective updates.
I never encountered this issue during testing.
As for the newspaper — it will become interactive in later stages. Not everything is interactive right away to maintain the logic of the story progression.
Let me know if this helps! :)
