The only text that changes color on my screen when firing in wattage mode is the wattage. The rest of the text stays the same. If my screen text is blue or white, the wattage changes to yellow while firing. If my screen text is yellow, the wattage changes to white while firing. I haven't yet used any mode other than wattage.anyone run into a bug on the SX550j that turns all the text to yellow, and then white while firing? It's inverted lol
