Ruskul Yea I'm with you on this one, I came across this the other week trying to make a clone of that One More Dash game, checking to see if one point in my circle is overlapping a point on the target.
From what I can remember, there was a thread on here somewhere where Ashley answered saying it was more complicated than it sounds to add that functionality. I think some of the better than me developers had posted some other ways of accomplishing it. Sorry I don't have the link at the moment, but I know there is one.
