I've had this happen with two users now, and it happened to one several times (2-3 times just this morning). When connecting to gotomypc (host has two monitors, both1080), the resolution on the main screen drops, and they end up with a smaller, square screen in the middle of their client screen. If I go to the host and adjust the resolution back, it goes back to normal. I don't know if they're able to make that change from their end (he says he can't, but I don't know if it's a technical or user issue 😁). Is there something we can do to avoid this? I thought that gotomypc would just scale the viewer window, not adjust the host resolution, but it wouldn't be the first time I missed something...
Also, for one of them, sometimes disconnecting and reconnecting fixes it. But not always. And one of the users came in after having the issue at home, and in the office the host pc's resolution was still set wrong.
