Oil Overfill? How dangerous?

[David.Ullrich at ferguson.com]

OK, as you know, I'm having a problem where my oil light comes on at idle once warmed up. Give her just a tad of throttle to bump the RPM to around 1,000-1,100 and it goes out. The oil is 20w50 fresh from a dealer change. Well, Friday afternoon, I checked my oil. They OVERFILLED it! It's over the "max" mark by about 1/2". Just how bad/dangerous is this? The car has the 2.3 NG engine in it and is 100% stock. Also, could this be the cause of my oil light coming on after the engine warms up?
