Thanks, Jonathan. Using Matt Gemmel's idea of making an attached window, I wrote a class that makes a fat arrow with a blue gradient that looks like the one you get when you click a menu item after searching in Help. Now, I'd like it to be animated, like Apple's fat blue Help arrow, moving slowly in a little circle. In Matt's code, he moves the attached window by re-creating it. I could do this brute force, offsetting the frame with x=cos(wt) and y=sin(wt). In the Core Animation Programming Guide > Animatable Properties, it says that 'position' can be animated, and this has the effect of animating the frame. I've never used Core Animation. Is Core Animation the tool for this job or should I use my brute force?
