While installing the 3.1 ROMS and WB3.1 in my A4000, I decided to give my motherboard the switchover to PAL as the defacto standard. HAving never bothered to run workbench in the PAL modes up until now, all I can say is NTSC is the most flickery POS I have ever seen. Super Hi res mode in PAL has barely barely noticeable flicker. I know it's kind of a moot point these days, but man did the US and anyone else on that crappy NTSC standard drop the ball.
