Changing the Keyboard layout in Host or Virtual machine to US should rectify this.
Thanks for your response, though I'm skeptical: there was a long thread about this issue elsewhere on this forum and many things like this were recommended and didn't help. It did turn out to be a bug, which was fixed in version 11 and seems to have made a comeback with one of the recent updates.
Nevertheless, I'm willing to try. How/where do I ensure my keyboard layout is configured as you suggest?
