Reading this, I was thinking "Windows 10 system tray ,, double hides Icons .. "
You understand; Windows 10 has the SysTray Icon where it hides icons and you hover over that to see what other programs *it* has decided to hide again ... but you also say the same for Win7 and I don't know if that does the same ?
Also, this is related to suspend/hibernate and I know openvpn has had trouble with
resume in the past.
I recommend you report this to the openvpn-users mailing list where the developers will be able to advise you.
