JohnDeoVR I could be watching a video, make a few adjustments, then hide the adjustments / menu. Watching the video then I want to skip to another part or make an adjustment to angle/height, etc... I can't get the menu to re-appear. Sometimes I can but clicking a button won't do anything. That's when I did take the headset off, and stopped/restarted WMR and/or SteamVR and that would often get it working again.
Like I said, I got Whirligig to work perfectly. Never lost the mouse. on my most recent testing. Running it in Directshow with LAV filters - if that makes any difference. This was all done on an HP Omen 15t w/ Nvidia 2060 - FWIW.
