I've a problem when I connect using UltraVNC to a PC that I use with ProtonVPN. Please don't get me wrong: I'm not connecting to that PC using UltraVNC thru ProtonVPN: both PCs are in the same LAN.
I want to connect to it, and then make it open a ProtonVPN session.
When I left click on the ProtonVPN tray icon, a small window like this (but without the red arrow) should show:

But, I can't see it. Nothing shows.
Can someone please give me a clue about if some UltraVNC option would fix this?
Thanks
