>I am trying to use Nick's gridhighlighter in a grid that contains different types of item lines, colour-coded by item type with a background colour using dynamicbackcolor. I would like to use the gridhighlighter to highlight only by setting forecolor to white and boldface, and back to normal (depending on item type) when un-highlighting an item. Is that possible?

Peter, set your gridhighligter instance properties:

lSetBackColor = .F.
cHighForeColor = RGB(255,255,255)
lsetBold = .T. && default value
