This serious and boring issue is still occuring, again and again.
After trying to pickup some old Defaults file with no success, I saved all preferences I could and deleted Defaults file then. Relaunched Nuendo and manually reinstalled all preferences. I could open panners windows then.
Well, how long did it work, I just don’t know. But it doesn’t work anymore today. SurroundPannerV5 windows are displayed in opened windows list, but just non visible, as ever.
Deleted Defaults once more. Copied the last one I saved, renamed it to “Defaults.xml”, pan windows are back… for a little while I guess.
Anybody using pan windows ?
