I have a particular Windows app (SDL Trados) that recently has started disappearing from the Mac's Switcher (and from my screen) when I'm in Coherence. It remains visible if I stay in the app, but it vanishes if I switch away from it. The only way to get it back is to exit Coherence. The odd thing is that another Windows app (Word) does not have this behaviour. Any clues? (Latest Parallels, latest Mac OS Big Sur build, latest Windows 10).
