Mine was also detected. Tho Alaplaya is going thru alot of issues with X trap.Tons of people are being banned left and right and they do not even hack. People are complaining all over the s4 fourms about it. Some people on the s4 fourms are saying that X trap is extremly sensetive and goes off for basically anything.
Also when I did not have the item manager up and had msn messanger up it also said hack detected and I got temp banned for a few days...
So it might not be the item manager and just Alaplaya failing once again.
