Booting in Safe Mode:
Spacebar control is restored but the Hand only appears when a pan input is provided. i.e. The hand icon does not appear when the spacebar is down, only when the pointer moves and the document is dragged.
Other applications that also use the spacebar to pan do change the cursor on spacebar-down, as VW used to do.
After a normal reboot, it’s still working as above.
Clearly there is no immediate incompatibility so what will be interesting is how the system behaves over time. Consequently, I am keeping VW running in the background and monitoring its behaviour as I launch apps and resume normal operations.
