Once you open the console for the lab environment you should see options like this -
The mouse cursor icon should help you in toggling the host point.
Personally, I have found enabling host point beneficial and I use it always while working on labs.
The host point hides or enables the mouse cursor. That works.
That is not the issue.
In DO450 4.5 the host point is the small circle as shown in the screen shot.
Is this a bug or a feature?
