Thanks Terence! (I know! I heard David’s ‘never download a dot zero update’ advice the day *after* I went and did it!) I’ll try disabling the gpu setting. (The option is grayed out on my monitor, but maybe with monitors off it will work.) Also, I got another tip – ‘turn off rulers’ – that seems to solve the ‘white out’ problem. If I don’t have to measure anything! Cheers! -S
