[constantly?]: Don’t know yet. I saw it that once so far, and since I decided to live with it and press on, it affected me for an extended period, so I reported it right away. Maybe premature, although guaranteed it happened, so I wondered who else was seeing it, and didn’t see anyone else complaining, so I thought I should make it known. I should really check for repeatability. Haven’t found the time yet, to go again.
[Addons?]: Marketplace items…? Good point. I’ve loaded some aircraft and scenery from the MSFS Content Manager. Since I use MSFS infrequently, I’m not honing my advanced user skills, so I’m not sure how to back them out…
[other programs?]: I run FlightEvents to follow along with ForeFlight. I usually have the Task Manager window open.
