Ever since v16, there’s been a weird bug in 010 Editor. Whenever I middle-click on a tab to close it, it moves the entire 010 Editor window to one of my other monitors (I have 3). It doesn’t close the tab either FWIW.
It seems to consistently cycle through the monitors - I can chase the window using my mouse, middle click on the tab again and it’ll move to the next monitor.
I can’t see a way to remap this behavior at all - but the fact it cycles monitors makes it feel like a bug report more than a feature request… but I could definitely be wrong.
