I'm unsure if this is a bug or user error, but I have Ableton open on my main monitor (screen 1), and MiniMeters open on my laptop screen (screen 2). When I remove my main monitor display, it shifts everything to the laptop screen (screen 1). Now, if I open MiniMeters again, for a split second, it opens in the top left corner and then hides itself, almost as if MiniMeters still thinks there are two screens connected. I've tried using Win + Arrow Keys to move MiniMeters, but it seems to have no effect.
Hey! Sorry you're running into this. I previously had it automatically move windows back on screen when a display was disconnected, but a related issue caused me to default to turning that off. This will be fixed in the next update (0.8.13) which will be out soon.
In the meantime if you're the type to mess around with settings files you're welcome to navigate to `%AppData\MiniMeters`, open `settings.json` and add or set `"reposition_offscreen_windows" to true` Alternatively feel free to reach out on the MiniMeters Discord and I can help you modify the file, or modify it and send it back to you. Sorry for the inconvenience.
