red coloring on overexposed shots in ps5

[12sndsgood]

so i was working on some pics when my 6 year old helper decided to hit a bunch of keys. i believe it turned on some type of filter that shows overexposed areas of the picture as solid red. at first i thought maybe it was just the one picture having problems. but then as i opened a few more i noticed any blown out spots as solid red. if i adjusted the exposure or recover to bring them back the red would start going away so im thinking this is a setting on cs5. going thru the help right now but havn't found anything yet. any help?

Try hitting the o key...that should turn on/off the 'highlight clipping warning'.

The current Photoshop CS5 is actually Photoshop 12 (Ps12).
