I just updated last night to the latest build: 6/07/2017 Build ID : 1941092 which includes a fix: VR Removed mouse cursor while driving. I run in VR with HMD only selected, so just get a black window on the monitor screen. Now when I press Escape while driving, which pauses the driving and brings up the menu to return to the pit, instant replay, restart race, etc., the mouse pointer is not shown in VR so the menu is very hard to use. The mouse pointer is shown on the black window on the monitor and if you move it to the right position the options in VR are highlighted in yellow and clicking on them does work, but this is not easy. The VR mouse cursor needs to be switched back on temporarily when showing an on-screen menu in driving mode. (Personally, I didn't mind the mouse pointer being shown in driving mode, though I have seen others comment on it - I just moved it out of view behind me.)
Good to know they're on it. It's very frustrating. I think we've had more updates and fixes over the last few weeks than we got over the last few years! #justsaying. Thank you S397
