Periodically [ctrl] and [space] stop working as key modifiers for pan and zoom, bringing progress to a complete halt. Sometimes stopping and restarting XD resolves it, sometimes (like now) it doesn't. I'm at a loss as to which process to kill in task manager as there's no obvious XD process. Plenty of random Adobe processes though. This is very annoying. Version 188.8.131.52 CC Sync 184.108.40.206.
We are sorry to hear you are having trouble using pan and zoom in XD. Would you mind telling us if you're having issues with these buttons in XD only or with other apps as well? Could you please check if any anti-virus is causing the problem?
