Hi. I'm going crazy, because almost every time I'm switching from host OS to guest OS. Ubuntu is opening below attached error message (on 16.xx LTS & 18.04 LTS) or GNOME help page (on 18.04 LTS). Dear Parallels Support Team, please let me know how can I solve this problem? https://images91.fotosik.pl/85/d9ff61c0d3dc300fgen.png Problem was observed on: - Host OS: Mac OS High Sierra - Guest OS: Ubuntu 16.xx LTS & Ubuntu 18.04 LTS - Parallels 13 Desktop (not Business Ed.) & Parallels Desktop Business Edition 14
https://images91.fotosik.pl/85/3d9ea055e432f5a3med.png I think I found a solution. As depicted above the "Num Lock" key binding was set for Ubuntu "Launch Help Browser" action. I disabled this key-bidding and see no more unwanted windows. Seems that Parallels send to guest OS some key-event which Ubuntu mapped to 'Num lock' key
