I am (likely) being accused of cheating by my professor, what do I do?
First, don't assume that the concerns about one person are necessarily the same as concerns about another. It may just be coincidence.
Second, the history is what it is. If there is some &quot;evidence&quot; that you did something wrong you will just have to explain it as best you can and live with the consequences.
It may well be that the monitoring system gets a report of open windows/apps but can't distinguish what is visible to the user from what is not.
Explain your actions. I suggest honestly. If you didn't cheat, then insist on that and don't agree to &quot;lesser penalties&quot; if you admit to something you didn't do.

Also note that statements about what automated systems do or don't do can be checked experimentally and/or by contacting the vendor.
