Ahhh thanks. I'll try that. The reason I want to have the highlight warning blink on the histogram , but not on the main full sized LCD is because once I get something dialed in, I like to view the comp on the full screen. The constant blinking annoys me. Also, sometimes clients like to see the LCD screen--because their point and shoots have it and it's Pavlovian.
Anyway, thanks for the tip on the +.
