Please see attached screenshots, I hope this is what you are looking for? These were taken all while fsx.exe was "not responding" (in red).
Static screenshots are not very helpful, because I would have to look at the file monitor for the whole duration of the load. I'm sorry, but if you don't want to do a Teamviewer session for whatever reason, there's nothing else I can help you with other than what we already said.
I'm sorry, but if you have reasons to believe TM could be considered a security risk, that's far from it, because it's a product that is used in the Enterprise world quite a bit, and it's specifically designed for remote assistance.
- Nobody can connect to your system unless you start Teamviewer.
- The password changes *every* session so, it's not as if (even if you forget to quit from Teamviewer) that once you gave the password, someone could enter in your system again.
So, it's totally safe to use, and it's very well known and used in the corporate world so, there are really no reasons not to use it.
