Hi, thanks for sharing this issue.

I hope you don't mind me asking a few questions to narrow this down.

- When you talk about the green dot in the bottom right corner, do you mean the 'Corner spinner' that shows the engine working? (Which can be a range of colours, depending on the state of the engine)
- Is the spinner permanently gone? Or does it disappear intermittently?
- Do you consistently see the inline coverage markers showing in the IDE? Do they disappear at all?
- Are you running with DPI scaling? Do you have different scaling per monitor?
- Does this happen for you for ALL solutions? What about a new minimal one with a single test?
- Would you be able to submit an NCrunch bug report after this has happened to you? The log may yield useful information
