Sorry for the waste of bandwidth - I found it in the end: it's all to do with
undetected errors in the code. In one case I had a badly formed statement that
compiled without problems - I had put 'to' instead of 'into' - so the rest of
the handler was skipped; in another case I had called iPhoneControlSet with a
bad parameter, which again caused the script to stop executing.
I find this kind of debugging tough: I am using very clunky debugging methods
because I have not yet understood the following (from the LC iOS Release Notes):

All these tests have just been with the 5.1 iPhone simulator, and I haven't yet
found the Console app. Can anyone help me?
