Yes, basically "call method" is leaky when an Objective-C object is handed
to AppleScript, and there is nothing you can do about it. (In an app of
mine, I was actually able to spot the specific leak; using ObjectAlloc, I
was actually able to see Apple's code setting two extra retains on the
object and not releasing them.) And certain other actions (such as dynamic
menu creation) are leaky and there is nothing you can do about that either.
Such is "the price of frame" - i.e., you're using a framework, so you're
depending on someone else's code. m.
