Oops, I meant the button target as Kyle has already pointed out.

Just 10.6 for x86. 10.4 for PowerPC but the PowerPC version of my
app uses Carbon anyway.

The actual Cocoa code in my app is really just a few kilobytes. It's
not complicated at all so there is no pressure to simplify things by
using ARC. If this was a huge project with lots of new code to be
written, it would be a different matter, but it's really just a few
lines. So it's a nice exercise for understanding manual memory management
with Cocoa.
Of course, I might switch to ARC sooner or later but I first
like to learn and understand the old way of doing things... maybe this
also helps me to appreciate ARC more once I start using it ;)
